IgG contributes to 10−20% of plasma protein and is regarded as one of the most predominant serum protein. It consists of four subclasses: IgG1, IgG2, IgG3 and IgG4. The IgG structure possesses four polypeptide chains containing two identical γ heavy (H) chains and two identical κ or λ light (L) chains of 50kDa and 25kDa respectively. Papain and pepsin digestion yields two main fragments of the antibody: Fab (antigen binding fragment) and Fc (fragment crystallization tail).
特異性
This product was prepared from monospecific antiserum by immunoaffinity chromatography using Rat IgG coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities. Assay by immunoelectrophoresis resulted in a single precipitin arc against Anti-Rabbit Serum, Rat IgG, Rat IgG F(c) and Rat Serum. No reaction was observed against Rat IgG F(ab′)2.

生物化学的/生理学的作用
IgG (immunoglobulin G) antibody provides protection against bacterial, fungal and viral infections. Maternal IgG is transferred to fetus through the placenta that is vital for the immune defense of the neonate against infections. The Fc (fragment crystallization tail) region of the antibody is implicated in complement activation in which it elicits an immune response by binding to the Fc receptor on macrophages.

Emerging evidence suggests that intestinal stromal cells (IntSCs) play essential roles in maintaining intestinal homeostasis. However, the extent of heterogeneity within the villi stromal compartment and how IntSCs regulate the structure and function of specialized intestinal lymphatic capillary called lacteal

Of the five immunoglobulin isotypes, immunoglobulin G (IgG) is most abundant in human serum. The four subclasses, IgG1, IgG2, IgG3, and IgG4, which are highly conserved, differ in their constant region, particularly in their hinges and upper CH2 domains. These
