Cat#:PA-2113F;Product Name:Sheep anti-Mouse IgG (H&L) Antibody;Synonym:IgG; Ig gamma 1 chain C region; IGHG1; Immunoglobin heavy constant gamma 1; Immunoglobulin G; Ighg1; Immunoglobulin G, Heavy & Light chains;Background:IgG is a monomeric immunoglobulin, built of two heavy chains gamma and two light chains. Each molecule has two antigen binding sites. This is the most abundant immunoglobulin and is approximately equally distributed in blood and in tissue liquids, constituting 75% of serum immunoglobulins in humans. This is the only isotype that can pass through the human placenta, thereby providing protection to the fetus in its first weeks of life before its own immune system has developed. It can bind to many kinds of pathogens, for example viruses, bacteria, and fungi, and protects the body against them by complement activation (classic pathway), opsonization for phagocytosis and neutralisation of their toxins. There are 4 subclasses: IgG1 (66%), IgG2 (23%), IgG3 (7%) and IgG4 (4%).;Description:Sheep anti-Mouse IgG (H&L) Polyclonal Antibody;Host Species:Sheep;Species Reactivity:Mouse;Storage:Store antibody products at 2-8°C.
