QuicKey Pro Rat IgG(Immunoglobulin G) ELISA Kit (E-OSEL-R0005)

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat IgG. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Rat IgG are added to the micro ELISA plate wells. Rat IgG in samples (or standards) combines with the coated antibody and HRP linked detection antibody special to Rat IgG.Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450±2 nm. The OD value is proportional to the concentration of Rat IgG. The concentration of Rat IgG in the samples is then determined by comparing the OD of the samples to the standard curve.

Immunoglobulin G (IgG) is an antibody, which is a protein complex composed of four peptide chains - two identical heavy chains and two identical light chains arranged to form a Y type antibody monomer. Each IgG has two antigen-binding sites. IgG is the main antibody in blood and extracellular fluid that can control infection in human tissues. Plasma B cells produce and release IgG molecules. IgG is the only immunoglobulin that can pass through the human placenta, thereby protecting the fetus in the womb. IgG antibodies extracted from blood donor plasma can be used as intravenous immunoglobulins to treat immune deficiencies, autoimmune diseases, and infectious diseases.
