Application

Anti-Horse IgG (whole molecule)-Peroxidase antibody produced in rabbit has been used in:enzyme-linked immunosorbent assay (ELISA)HeV soluble Gindirect ELISA (HeVsG iELISA)

Biochem/physiol Actions

Immunoglobulin G (IgG) participates in hypersensitivity type II and type III.

Equine IgG antibodies mainly regulate mucosal and systemic immunological responses and thereby, provide protection against disease-causing pathogens such as Streptococcus equi, and the horse flu virus. Horse IgG may also function to control the advancement of EHV-1 infection .

General description

Horse IgG is a plasma B cell derived antibody isotype defined by its heavy chain. IgG is the most abundant antibody isotype found in horse 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.

An immunoglobulin has two heavy chain and two light chain connected by disulfide bond. It mainly helps in immune defense. It is a glycoprotein. IgG is a major class of immunoglobulin. Horse IgG has different subclasses, IgG2a, IgG2b, IgG2c, IgG1 and IgG(T). Compared to other IgG molecules, IgG(T) has more carbohydrate content. In healthy individuals, total IgG is dispersed equally between circulating plasma and interstitial fluids.
