The Human IgG (Immunoglobulin G) ELISA quantitates IgG in serum and plasma.
原理方法
The Human Immunoglobulin G (IgG) solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the concentration of Immunoglobulin G (IgG) in biological samples. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are added into these wells and bind to the immobilized (capture) antibody.
The sandwich complex is formed by the addition of a second (HRP-linked) detection antibody specific to Immunoglobulin G (IgG). Excess reagents are washed from the plate.
A substrate solution is added that reacts with the enzyme-antibody-target complex to produce a measurable signal. The enzyme-substrate reaction is terminated by the addition of stop solution. The intensity of the signal, measured spectrophotometrically at 450 ± 2 nm, is directly proportional to the concentration of Immunoglobulin G (IgG) present in the original specimen.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

Human IgG, also known as human immunoglobulin G, is an antibody that is produced by the immune system in response to antigens. It is the most abundant immunoglobulin in the blood and plays a key role in defense against pathogens. IgG works by binding to specific antigens and promoting their clearance from the body through various mechanisms, including phagocytosis and complement activation. IgG is also involved in other immune responses, such as antibody-dependent cellular cytotoxicity and neutralization of toxins. Human IgG can be used in research to study the immune response to pathogens and to develop diagnostic tests and therapeutic interventions for infectious and autoimmune diseases.
