Immunoglobulin is a glycoprotein, with two heavy chain and two light chain connected by disulfide bond. IgG is a major class of immunoglobulin. It has five subclasses of IgG- IgG1, IgG3, IgG2a and IgG2b. Affinity isolated antibody is obtained from rabbit anti-pig IgG antiserum by immunospecific purification which removes essentially all rabbit serum proteins, including immunoglobulins, which do not specifically bind to pig IgG. Anti-Pig IgG is then conjugated to peroxidase by protein cross linking with 0.2% glutaraldehyde.
Immunoglobulin G (IgG) participates in hypersensitivity type II and type III. It mainly helps in immune defense. Pig IgGs against target proteins are often used as primary antibodies in various research applications. Thus, secondary anti-pig IgGs conjugated to a detectable substrate are useful tools for the analysis of target proteins. Rabbit anti-pig IgG (whole molecule)-peroxidase antibody binds to pig IgG.
