ELISA

The Human IgG Subclass Profile (Hu IgG) ELISA quantitates Hu IgG subclasses in human serum or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu igG1, IgG2, IgG3 or IgG4.

Principle of the method

The Human IL-10 US solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody, binding to the target on a different epitope from the capture antibody. A conjugated enzyme has been incorporated into the assay. After incubation and washing steps to rid the microplate of unbound substances, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target 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.
