Jason Huang Antibody Variations AP Biology EO1 Explain how variations within a class of molecules allows for a greater diversity of functions. Focus on antibody variations. During an immune response‚ the white blood cells including T cells and B cells bind to the antigen. Antigens are chemicals released from invading pathogens or toxins. The binding of antigen to the antigen receptors of T cells or B cells help activate and secrete antibodies to bind to the antigen receptor protein on the

(Enzyme-Linked ImmunoSorbant Assay) ELISA is abbreviated term for Enzyme-Linked ImmunoSorbant Assay. This procedure is one of the most widely used methods in clinical immunology assays to detect the presence and absence of certain antigens or antibodies and also to quantify them when necessary. Quantification can be done in a range of microgram (µg) to nanogram (ng). The ELISA procedure takes advantage of the fact that most proteins will bind firmly to the surface of different kinds of plastic

lymphocytes with three individual monoclonal antibodies directed at the T4 glycoprotein blocked cell infection by LAV. This blocking effect was specific‚ as other monoclonal antibodies—such as antibody to histocompatibility locus antigen (HLA) class II or anti-T-cell natural killer (TNK) target—directed at other surface structures strongly expressed on activated cultured T4+ cells‚ did not prevent LAV infection. Direct virus neutralization by monoclonal antibodies was also ruled out. These results

these hybrid cells have got the ability to produce antibodies due to the B-lymphocyte genetic material and also capacity to divide indefinitely in the culture due to the presence of tumour cell or myeloma cells involved in the production of hybrid cells. Therefore‚ these hybrid cells produced from hybridoma technology are cultured in laboratory or passaged or sub cultured using mouse peritoneal cavity and these cells produces monoclonal antibodies‚ and this technology is called as hybridoma technology

These antibodies then begin to bind to antigens on the patients own cell surface. Once these are binded they are recognized as intrinsic or extrinsic. During this phase the cells can act as antigen presenting cells. Another form of Type 2 hypersensitivity is called antibody-dependent cell-mediated cytotoxicity. (The reactions ran can take hours to a day.) Type 4 hypersensitivity which is an independent antibody and its reactions take 2 to 3 days. Unlike others

Immunohistochemistry or IHC refers to the process of detecting antigens (e.g.‚ proteins) in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues.[1] IHC takes its name from the roots "immuno‚" in reference to antibodies used in the procedure‚ and "histo‚" meaning tissue (compare to immunocytochemistry). Immunohistochemical staining is widely used in the diagnosis of abnormal cells such as those found in cancerous tumors. A video

Radioisotopes are radioactive isotopes of an element. An isotope is an element’s atom that has the same number of protons and electrons‚ but a different number of neutrons‚ causing the atom to be unstable. With radioisotopes‚ they can occur naturally‚ but most often are formed artificially by altering the atom. Scientists measure the rate of which radioisotopes decay at by using the term half-life. This refers to when one-half of the radioactive material has decayed. When the word radioactive comes
