A reaction between an antibody and soluble antigen-forming lattices is called?
precipitation reaction
What is the relationship between antigen and antibody?
Basically to explain this, an antigen is any type of pathogen that causes disease, while an antibody is something that combats against the antigen.
What is the basic principle of the antigen-antibody reaction?
-the principle of antigen-antibody reaction is a process of the immune system in which immunoglobulin-coated B cells recognize a specific antigen and stimulate antibody production. T cells also play an essential role in the reaction. An antigen-antibody reaction begins with the binding of antigens to antibodies to form antigen-antibody complexes. These complexes may render toxic antigens harmless (neutralization), agglutinize antigens on the surface of microorganisms, or activate the complement system by exposing the complement binding sites on antibodies. Certain complement protein molecules immediately bind to these sites and trigger the activity of the other complement protein molecules, which cause antigen-bearing cells to lyse. Antigen-antibody reactions may start immediately with antigen contact or as much as 48 hours later. They normally produce immunity but may also be responsible for allergy, autoimmunity, and fetomaternal hematologic incompatibility. In the immediate allergic response, the antigen-antibody reaction activates certain enzymes and causes an imbalance between those enzymes and their inhibitors
What Is the difference between antigen binding site and paratope?
Antigen binding site or epitope is a part of an antigen that is recognized by the antibody. Paratope is a part of an antibody that binds on epitope.
What is the different between polyclonal antibody and antiserum?
polyclonal antobody is the antibody produced for many or non specific antigens but antiserum is the antibody for a specific antigen
What directs the antigen-antibody response by signaling between the cells of the immune system?
Lymphokines
What is the reaction between antibody and particulate antigens called?
agglutination reaction
What is the difference between agglutinogens and agglutinin?
When the immune system cause cross linking of cells or particles an agglutination reaction occurs and the responsible antibody is an agglutininAgglutinogens are1. any substance that, acting as an antigen, stimulates the production of agglutinin.2. the particulate antigen used in conducting agglutination tests.
What happens when the epidermis and the dermis are destroyed?
difference between an antibody and an antigen
What is the difference between alloimmunization and isoimmunization?
the autoimmune reaction is the reaction between the antibody and antigene when both come from the same body but the isoimmune reaction is between the antigene and antibody produced for the same antigene ( the same according to the type but not the immunity )
What is the difference between hepatitis B surface and hepatitis b antigen?
When your body is introduced to the Hepatitis B virus, the virus is considered the antigen (the surface antigen)and this should trigger your immune system to develop antibody against this antigen to destroy it. Most people do develop Hep B surface antibody when infected with the Hep B virus. Some people do not develop the antibodyand go on to have only circulating Hep B surface antigen - which means they are a carrier and can continue to have the virus and infection. For the majority of the population that develop the Hep B surface antibody, this conveys immunity to the virus for life.
What is the principle of radioimmunoassay?
As the name suggests there is an antigen - antibody reaction between the antigen (Hormone) of interest and its specific antibodies raised from laboratory animals. The quantum of antigen-antibody binding is monitored using a radiolabelled antigen or antibody. In brief the RIA kit contains test tubes which have been coated with the antibody. To these tubes, standards or samples are added (usually 25 to 200 ul volume) along with the tracer, The contents are incubated for 1 - 2 hours and the tubes are emptied by decanting the contents or aspirating. The tubes are washed with the wash solution provided and are counted in a gamma counter. The counts obtained for various known standards used in the assay are utilised for generating a dose - response curve and the unknown concentration in serum samples are extrapolated from the data. \ -THIOCARE
