Omalizumab, more commonly known by the trade name Xolair, is a monoclonal therapeutic antibody that is currently used to treat severe allergic reactions in diseases such as asthma and chronic idiopathic urticaria. The drug is currently produced at a manufacturing site in France through a partnership between Novartis and Genentech (Novartis). In order to produce this antibody, mice were injected with human IgE. The B cells of the mice were then harvested. The B cells were then fused with myeloma…

Rituximab is an antibody that is primarily found on the surface of B cells in the immune system. It destroys B cells and thus is used to treat diseases that are characterized by B cell disorders e.g. overactive B cells, excessive numbers of B cells, or dysfunctional B cells. Rituximab use has been associated with increased risk of hepatitis B virus reactivation in patients who are negative for hepatitis B surface antigen (HBsAg) and positive for anti-hepatitis B core antibody (anti-HBc). The…

would normally not provoke an immune response unless in a diseased state. In AD, the immune system fails to differentiate between self-antigens and foreign antigens and an immune response is produced when the body attacks its self antigens with antibodies made against it, resulting in tissue…

The Hepatitis C Antibody Test and The Hepatitis C RNA Qualitative Test. The Hepatitis C Antibody Test is screening test on your blood to see if you have ever had Hepatitis C. The tests check to see if antibodies are detected in your blood. If the test shows negative, then you have never been exposed to Hepatitis C and more testing is not necessary. If the test is…

autoimmune diseases. Each of the four drugs, infliximab, Adalimumab, Etanercept, and Certilizumab, have different antibody structures, leading to differences in function and binding abilities. The drug infliximab is a chimeric monoclonal antibody, containing 25% mouse-derived and 75% human-derived amino acids. The drug Adalimumab is a fully human monoclonal antibody containing an IgG1 antibody, proficient at complement fixation and Fc-receptor binding. Etanercept is a genetically engineered…

healthy or unhealthy. An unhealthy cell is infected, and once the infection is detected the immune system sends cells called antibodies to respond and terminate the unhealthy cells (Primary Immune Deficiency Diseases). If the antibodies do not respond, then a bodily infection will occur. The antibodies are located sporadically throughout the body. All of the antibodies begin in the bone marrow, and they mature and move to the skin, bloodstream, thymus, lymphatic system, spleen, and mucosal…

V beta 17 genes as a foreign antigen and made antibodies that would bind to the V beta 17 on the T cells. Afterwards, they isolated these antibodies and had a tool that they used to find v beta 17 because these antibodies bonded specifically to V beta 17. They attached a tag which would fluorescence green when a bright blue light was shined on it. Whenever a bright blue light was shined to this chemical it would glow green. Then they used the antibody to attach to a T cell that has V beta 17 as…

In this research paper, the functional relationship between protein named Albert and Alice will be prove using two advance techniques. Most of the molecular processes within the cell are carried out by protein-protein interaction (PPI), diseases such as cancer, Alzheimer’s disease can caused by abnormal PPI. As prior knowledge has advocate that this two proteins may have similar cellular pathway, therefore understanding if they have PPI becomes vital. There will be two methods described in this…

system, different antibodies, and color changes to detect immune responses in the body. CPLi, or Canine Pancreatic Lipase Immunoreactivity, is a specific lipase that is only found in canine pancreatic tissues. The CPLi ELISA snap test is made by Idexx and is used to measure the concentrations of pancreatic lipase in the serum of the patient. An antibody elsa test works when a blood sample and the conjugate specific for that test are combined together. The conjugate contains an antibody that…

antigens or pathogens. Antigens can also stimulate the production of antibodies. Antibodies have the capability of recognizing and destroying pathogens. However, antibodies are rarely ever involved in cell-medicated immunity. Cell-medicated immunity involve T cells and responds to viruses, tumor cells, or transplanted cells. There are also two types of immunities: active and passive acquired immunity. Active acquired immunity is antibodies being produced…
