一般描述

IgG (immunoglobulin G) antibody exists in four subtypes: 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. Limited digestion using papain cleaves the antibody into three fragments, two of which are identical and contain the antigen-binding activity. They are known as fragment antigen binding (Fab) fragments. These fragments contain the light chains paired with the VH and CH1 domains of the heavy chains. The variable region of the IgG antibody is specific to antigens and is highly conserved. It is abundantly present in mother′s milk. IgG contributes to 10−20% of plasma protein and is regarded as one of the most predominant serum protein.
This product is prepared by labeling high quality F(ab′)2 fragment of goat anti-rabbit IgG (H+L) with our superior near-IR fluorescent dye CF680. CF680 is brighter than other spectrally similar dyes. Most importantly, antibody conjugates prepared from CF680 have by far the best signal-to-noise ratio than antibody conjugates prepared from other spectrally similar dyes. Please also check out our CF680R, an extremely photostable rhodamine-based near-IR dye.

生化/生理作用

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. IgG antibody has its function similar to IgM antibody in complement system activation. IgG is involved in hypersensitivity type II and type III. It helps in opsonization, complement fixation and cell-mediated cytotoxicity.
