The activity of the antiserum is directed to human IgG4 subclass. Precipitating polyclonal sheep antisera to human IgG4, subclass specific Total protein and IgG concentration in the antiserum are comparable to those of pooled sheep serum. Antibody titre: The antigenic differences between subclasses are considerably less pronounced than those between classes or betw
纯化方法
Delipidated, heat inactivated lyophilized stable whole serum Immunoaffinity adsorption with insolubilized highly purified myeloma proteins of the other subclass or other serum proteins as required.
免疫原
Purified homogenous IgG4 is isolated from human serum. Freund's complete adjuvant is used in the first step of the immunization procedure.
In precipitating techniques as immunoelectrophoresis and double radial immunodiffusion to identify and measure the concentration of IgG4 subclass in serum or other body fluids. Human IgG constitutes about 75 % of the total Immunoglobulins in the serum of normal adults. It consists of four subclasses which are distinguished in isotypic heterogeneity of the gamma chains, and in physicochemical, biological and effector properties. The term
