html An antibody also known as an immune globulin (Ig) is a protein that a B Lymphocyte secretes in response to a non-self antigen. Every antibody is a Y-shaped molecule‚ made of four polypeptide chains (quaternary). Every mammal is able to make millions of different antibodies each with a different pair of binding sites for one type of antigen only. Antibodies are produced by white blood cells; they are used to help fend of attacks by pathogens. The antibodies are created using

followed by an enzyme-labeled antibody. This type of assay generally makes measurement of crude samples difficult‚ since contaminating proteins compete for plastic binding sites. Indirect ELISA (2) Indirect ELISAs also involve attachment of the antigen to a solid phase‚ but in this case‚ the primary antibody is not labeled. An enzyme-conjugated secondary antibody‚ directed at the first antibody‚ is then added. This format is used most often to detect specific antibodies in sera. Competitive ELISA

An Investigation in Monoclonal Antibodies Meena Henen Introduction One of the major medical concerns of the century has been finding a cure for cancer. Scientists have made progress in solving the cancer puzzle with the innovation of procedures such as chemotherapy and various scanning methods‚ but no one has yet found a definite solution. Possibly the newest discovery in the cancer field has been monoclonal antibodies (mAbs). Nicknamed “magic bullets‚” mAbs have

Antigens vs. antibodies An antibody is a protein produced by a host to bind to foreign particles and inactivate them. Ideally‚ the antibody binds to only their specific antigen. Antigens are defined as anything that makes the immune system respond by producing antibodies. They are often viruses‚ bacteria‚ or fungi‚ but can sometimes be dust‚ chemicals‚ pollen‚ or food proteins that cause allergic reactions. (Antigens that cause allergic reactions are called allergens). An epitope is the part of

functions of antibodies Antibodies also known as immunoglobulins are secreted by plasma cells and B lymphocytes from the bone marrow and the lymphoid organs. The effector functions of antibodies are determined by the constant regions of the heavy chain. There are five different isotypes known in mammals to perform different roles and to direct a specific immune response for the antigen encountered. The binding of antigens to the variable regions will trigger the effector functions. Antibodies are only

1. What are antibodies and why are antibodies ideal for targeting? An antibody‚ also known as an immunoglobulin‚ is a large Y-shaped protein used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. The antibody recognizes a unique part of the foreign target‚ termed an antigen.[1][2] Each tip of the "Y" of an antibody contains a paratope (a structure analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen

Briefly describe the four categories of antibody effector functions. One of the several means of protection of the body against pathogens is the activation of B cells and their generation of antibodies. These antibodies can be involved in four main functions: neutralization‚ opsonization‚ complement fixation and mediation of cytotoxicity. Neutralizing antibodies are the ones that block pathogens from gaining access to the cell by binding to receptors that the pathogen uses for this purpose. In

Antiphospholipid Antibody Syndrome When you think of your body attacking itself‚ what comes to mind? Many people have a hard time understanding how your own body would attack itself and how it would do it. Your immune system plays a big role in your everyday life to help protect you from the outside world to prevent you from getting infected with any living bacteria or virus. Your body is capable of producing and breaking down many things‚ but it’s also capable of destroying itself with autoimmune
