The Mouse Immunoglobulin A (IgA) ELISA quantitates IgA in serum and plasma.
Principle of the method
The Mouse IgA 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, a substrate solution is added that reacts with the enzyme antibody target complex to produce measurable signal. The enzyme substrate reaction is terminated by the addition of stop solution and the color turns yellow. The intensity of this signal, measured spectrophotometrically at a wavelength of 450±2 nm, is directly proportional to the concentration of target present in the original specimen.
