IgG抗体亚型是免疫系统中最丰富的血清免疫球蛋白。 它由B细胞分泌，存在于血液和细胞外液中，可防止细菌，真菌和病毒引起的感染。 母体IgG通过胎盘转移到胎儿，这对新生儿免疫防御感染至关重要，胎盘通过沉淀和凝胶过滤技术从正常人血清中纯化而来。
IgG antibody subtype is the most abundant serum immunoglobulins of the immune system. It is secreted by B cells and is found in blood and extracellular fluids and provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defence of the neonate against infections
Human IgG is purified from normal human serum by precipitation and gel filtration techniques.
Purified human IgG has been used :-
• as blocking antibody for flow cytometry
• as negative control in chromatin immunoprecipitation assays
• to precipitate IgG in human larynx epidermoid carcinoma cells by immunoprecipitation
• as a standard in enzyme-linked immunosorbent assay
Immunoglobulin G (IgG) regulates the immune responses such as phagocytosis and is also involved in the development of autoimmune diseases. IgG1 regulates complement fixation in mice.
