Mouse IgG is a plasma B cell derived antibody isotype defined by its heavy chain. IgG is the most abundant antibody isotype found in mouse serum. IgG crosses the placental barrier, is a complement activator and binds to the Fc-receptors on phagocytic cells. The level of IgG may vary with the status of disease or infection.
Biotin:avidin second antibody signal systems involve the conjugation of biotin to a secondary antibody. Once the secondary antibody binds to a target primary antibody in an immunochemical assay, the signal is developed by allowing avidin which has been conjugated to an enzyme or signal molecule to bind to the antibody associated biotin molecule.
