Antibody

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...

Effector Functions of Antibodies

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...

Elisa and Antibody

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 ...

Flow cytometry and important of measuring antibody titre

to detect the presence of Feline Panleukopenia Virus (FLPV) in the infected animal. The antigen (marker) of the virus on the surface of leukocytes of infected animals is detected using monoclonal antibody. Monoclonoal antibody is used due to its ability to produce large amounts of high specific antibodies that is useful to detect antigen in a tissue. The FPLV antigen is detected using anti-FPLV VP2 MAb 2D9, whereas MAb 9F23 is used to detect the IL-2 receptor on infected cells (Ikeda et all, 1998)...

Elisa: Antibody and Bio-rad Protein Assay

(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...

Active Immunity

Active Immunity The production of antibodies against a specific agent by the immune system is known as active immunity. This particular immunity process is there to keep you healthy. Active immunnity can be acquired in two ways: naturally by contracting an infectious disease or artificially by receiving a vaccination. Active immunity is natural and permanent; protecting individuals from disease their entire lives. This process can take place quickly by large amounts of medicines at one time...

Rh Incompatability

maternal blood can stimulate the mother’s immune system to produce anti-Rh antibodies. The anti-Rh antibodies are not produced in significant amounts until after delivery, therefore, a woman’s first infant is not affected. During the following pregnancies, when fetal and maternal circulatory systems are closely intertwined, the mother’s antibodies may cross the placenta. Hemolytic anemia can form when the mother’s antibodies enter the fetal circulatory system. Rh incompatibility is almost completely...
