Coursework. Immunoprecipitation Technique Coursework

. Immunoprecipitation Technique - Coursework Example The basic idea behind this technique is the separation of one single protein from a mixture of proteins. This could give us the idea of several characters of a protein such as its relative occurrence in a solution, it’s up and down regulation as well as its affinity for a specific antibody. Technique/Methodology Usually the process of immunoprecipitation can be completed in two ways: in sequential or in one step. Commonly the antibody on which the required protein is supposed to be attached is immobilized on a solid support such as beads. This solution containing the immobilized antibody and the beaded support is then incubated with the solution that contains the protein mixture containing the required protein. Incubation allows the specific protein to bind to then antigen and form a complex. This complex can then be separated from the solution and studied with different techniques such as ELISA or Western Blot according to the requirements. (Pierce Biotechnology 2011) (Pierce Biotechnology 2011) The diagrams courtesy of ‘Pierce Biotechnology’ show the process of immunoprecipitation starting from preparation of a solid support along with the antigen to the incubation and the formation of the antigen-protein complexes till the precipitation of the required protein. Types There main types of immunoprecipitation are: 1. ... pitation: Same as Chromatin only difference lies in the detection of RNA binding proteins Uses Immunoprecipitation has been useful in many aspects such as, It has enabled the scientists to know the activation of the proteins, their molecular weight and also separate some protein binding molecules too. This technique has also been helpful in detecting the abundance and activity of a protein. Protocols After collecting the required number of cells and washing them in ice cold PBS, the solution was spinned at 1000g at a temperature of 4 degrees. This would help in separating the supernatant fluid. The next step involves the resuspension of the pellet that contains the cells in an ice cold buffer after which the cells are lysed by centrifuge. The supernatant fluid is removed after spinning it again at 13000g at the same temperature for fifteen minutes. Bradford assay is then used to measure the quantity of the protein after the supernatant fluid is removed by spinning briefly. This super natant free solution is then incubated in a cold room with the required amount of specific antibody solution. After the addition of Protein A or G beads to the tube it is again incubated for an hour and then spinned briefly again so that further supernatant is removed. This beaded fraction is then washed with ice cold buffer and spinned to remove the supernatant and the resultant solution is kept for further analysis. BCL-2 Proteins Bcl 2 family proteins have been identified to play a major role in the process of cell death i.e. apoptosis. These proteins play both anti and pro apoptotic roles. Some members of the family are supposed to increase while some are supposed to decrease this process of apoptosis. In this project the interaction of Bcl 2 family proteins with PUMA have been

Personal Statement - Essay Example I play a number of sports, including uni-hockey, tennis, karting, skiing and golf. Sports enable a person to discover things about themselves that might elude them in normal life. They have taught me perseverance, courage and the ability to accept both victory and defeat with grace. As part of my extra-curricula activities I have taken part in yearbook activities and, as stated earlier took a trip to Mali in 2005 in order to teach children English. I learned what it is to be a stranger in a foreign land, and will empathize more with those I find in a similar position in my home country of Switzerland. I also learned the great benefits that accrue from helping others, both for society in general and the individual involved. The children I taught had little contact with the outside world before they met me, and expressed a fascination with this stranger in their midst that made me realize how privileged my life had been. Things I had taken for granted, such as always having enough to eat, living in a secure home and having a complete family cannot be relied upon by many of the children that I taught. Many had known times when they went hungry, when they feared for their lives because of civil strife, and when they did not know where they would be living from one day to the next. But none of them seemed to feel bitter or depressed about these facts. These experiences made them more eager to learn, especially the English language that they saw as a way to education and the way out of poverty. Their hope and enthusiasm taught me a lot about the most positive sides of human nature, especially those that can shine even when the physical circumstances of the person do not seem very promising. To conclude, I have led a full life up until now and am looking forward to the next stage of my education. My experiences in Mali showed me that hope, enthusiasm and optimism are the best manner to move forward in life. I learned as much from the children I taught

Written 2 - Assignment Example The genres where Memphis played were country music and blues, although she is widely known for her blues. She plays the guitar, banjo and drums. She learnt to play the guitar at 11 and banjo at 10 years. She also played the electric guitar. In interviews Minnie discussed how men would look down upon her.Her producers said that she was so rough she never took any nonsense from men and would beat them up (Garon, 313). Minnie herself said on a radio show that in some magazines she was described to play the guitar like man (Garon, 314). She did not want that because she knew women were good and should not be compared to men. On the other hand, Minnie says that her career as a woman in a male dominated area has been a good force to girls and women worldwide. She is a role model and a symbol of womens liberation and this has led to many females rising up to the occasion. This has affected her career positively in that she is a celebrity and quite respected for her contributions to the

Memo to training manager Essay Example | Topics and Well Written Essays - 1000 words

Memo to training manager - Essay Example As revealed from the Encyclopedia of Business and Finance, international marketing â€Å"occurs when firms plan and conduct transactions across international borders in order to satisfy the objectives of both consumers and the firm† (1). Obviously, as a global organization where our operations have been expanding in various countries all over the world, the strategies that were previously applied in our domestic markets are not sufficient and applicable in global settings. Accordingly, â€Å"unique environmental factors that need to be explored by firm managers before going global include trade systems, economic conditions, political-legal systems, and cultural conditions† (Encyclopedia of Business and Finance 1). These factors are macro-environmental factors that impinge on the performance of global organizations as they impact the host countries’ operations. For instance, trade systems encompass â€Å"regulations and restrictions include tariffs, quotas, embargoes, exchange controls, and nontariff trade barriers† (Encyclopedia of Business and Finance 1). Economic factors consider â€Å"industrial structure and income distribution. Industrial structure refers to how well developed a countrys infrastructure is, while income distribution refers to how income is distributed among its citizens† (Encyclopedia of Business and Finance 1). Politico-legal factors take into account the prevailing government structure, laws, policies and regulations, status of stability and impending threats. Finally, and equally important are cultural factors that include familiarity with the language, customs and traditions, values, and dimensions that affect practicing business in host countries. Just like any other objective for training and development programs, a specialized training for IM would prepare and enhance the skills, knowledge and abilities of all personnel on trading within international scope.

Gender Discrimination in the workplaceDifferences in earnings Research Proposal

Gender Discrimination in the workplaceDifferences in earnings - Research Proposal Example In earlier times, the gap between the pay of men and women was large. In recent times, this gap has narrowed to a great extent. What is this gap This is when men and women earnings are measured, a woman's earnings is always less than that of a man. Men earnings are used as a standard to measure female pays (Facts on Working Women, 2004). In 1992, women's median hourly earning was 79.4 percent of men's. While the female median wage or salary rate was 75.4 percent of their male equivalents. Annual women earnings in 1992 were 70.6 percent of men earnings (Facts on Working Women, 2004). These figures (adapted by the Bureau of Labor Statistics) prove that women are paid less. They were paid even less 40 years earlier than 1992. In these years, from early 1950s, women earnings have grown by 1.3 percent each year while men earnings have only grown by a 1.1 percent annually. This shows that the earnings gap narrowed in these 40 so years and continues to do so. The widest gap in earnings was found in sales job in the late 1990s. Only one out of every ten women was employed in such an occupation (BLS, 2008). The following graph is adapted from the Bureau of Labor Statistics. It shows women's earnings as a percentage of men earnings over the last 28 years, by age. The graph shows that women's earnings as a percentage of men's has generally increased over the last thirty years. The earnings gap has narrowed for all age groups. However, we must remember that employment patters consistently illustrate that women largely occupy lower-paid jobs than men, even after providing for changes in tastes and productivity. This paper will revolve around the question of discrimination in the workplace. Are women paid less than men The paper will discuss which gender is paid less in the workplace and is discriminated against. First, this will be illustrated by giving statistical information about differences in earnings. After this, reasons for such differences will be discussed and it will be evaluated why there is discrimination in the workplace. Discussion According to an economist's definition, discrimination in the workplace is when two people have equal productivity but different outcomes. These people are most likely to be a part of different groups. Like I mentioned earlier, it is a well known fact that women have been a target of discrimination in the workplace. Evidence of discrimination in the workplace is subtle. They can be analyzed by either direct testimonies or by studying statistical employment patterns (Jacobsen, 2007). Some people say that because of this discrimination they are also paid less in earnings than the men in same or similar organizations. But we must understand that men, obviously, are stronger; physically and sometimes, even mentally. Men are good in crisis. Most men have the attributes of natural leaders, for example, strong mindedness etcetera. Besides that, many women wish to spend more time with family and less time at work. They may not be as willing as their male counterparts to travel around the world to get promoted to higher positions. They might not be so comfortable with the idea of having to shift their homes in search of better job opportunities. Women might be more willing to take more time off from work and longer breaks to deliver and/or look after their babies. These are also some of the reasons

The Role of the Operating Manager in Information Systems Essay

The Role of the Operating Manager in Information Systems - Essay Example However, the system transformation process is not easy as an entire department that utilized the system is grounded to a halt, which means dealing with inconveniences of managing the functions manually (Khosrow-Pour, 2001). The main issue is in how to attain effective Information Technology Management within MSCC while sufficiently anticipating challenges and their solutions to guarantee business continuity and employees’ productivity. During the 1900, Midsouth focused on transportation systems and legislative decisions caused many communities to lack access to reliable transportation, halting the economic and business development. However, by 1930s, the charter included additional issues, thus transforming into an aggressive commercial advocacy firm by 1990s. These changes were accompanied by company growth in terms of human resources and profitability changed by 2000 to reflect a downfall in the annual budget by $250,000 and a membership of about 2,300. The main contributors included the internet bubble, loss of regional manufactures, and the economic downtime back then. Although, MSCC did not lose its position as a powerful business advocacy firm in 2000, the company’s management experienced the challenge of inability to fund annual operational business in line with the company’s aggressive growth. Lassiter, the Vice President in 2000 experienced a serious dilemma of staff and program retrenchment for an effective sales and marketing team, thus translating into less aggressively grown revenue in the firm. As an information Technology professional, Lassiter proactively sought for the solutions to the IS challenges that included misaligned marketing and sales support functions, restricted capacity of the current information system, and the arising concerns over security given that each staff member lacked access to data required for the operation of MSCC activities for sales and marketing. At MSCC, information technology is
