Protein G is an immunoglobulin (IgG) specific bacterial cell wall protein isolated from Streptococci (group G). Native proteins G consist of two IgG-binding domains and albumin and cell surface binding sites. Biotin is a water soluble vitamin that acts as a coenzyme for carboxylase enzyme reactions. Biotin deficiency results in deregulation of metabolic pathways and various physiological impairments. Biotin deficiency is known to cause birth anomalies indicating its important role in development and differentiation of embryos.
Protein G binds to antibodies reversibly and thus, it is considered in antibody purification. It is a 20 kDa protein.
Truncated - lacks albumin, Fab and membrane binding sites.
