The Human GAPDH ELISA quantitates GAPDH in serum, plasma, and other biological fluids
The Human GAPDH (Glyceraldehyde-3-Phosphate Dehydrogenase) 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 are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the binding of the second (detector) antibody to the target on a different epitope from the capture antibody. An antibody conjugated with enzyme binds the formed sandwich. 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.
GAPDH (Glyceraldehyde-3-phosphate dehydrogenase) is a catalytic enzyme commonly known to be involved in glycolysis. GAPDH exists as a tetramer of identical 37-kDa subunits and catalyzes the reversible reduction of 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphophate in the presence of NADPH. Apart from playing a key role in glycolysis, GAPDH is ubiquitously expressed and displays other activities unrelated to its glycolytic function. GAPDH is reported to be involved in the processes of DNA replication, DNA repair, nuclear RNA export, membrane fusion and microtubule bundling. Studies provide evidence of GAPDH playing an essential part in gene expression observed in apoptosis and as part of the cellular phenotype of age-related neurodegenerative diseases. Further, GAPDH is involved in other cellular processes ranging from membrane fusion, and neuronal apoptosis in cancer. GAPDH is reported to bind to a variety of other proteins, including the amyloid precursor protein, mutations in which cause some forms of Alzheimer's disease (AD), and the polyglutamine tracts of Huntingtin, the protein product aberrant forms of which are causative of Huntington's disease. Associations between GAPDH, actin and tubulin have also be reported. Since GAPDH is expressed at high levels in most tissues, it is useful as protein loading control in Western Blot analysis.
