Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate CYCS in samples. An antibody specific for CYCS has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyCYCS present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for CYCS is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of CYCS bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:Cytochrome c, or cyt c (horse heart: PDB 1HRC) is a small heme protein found loosely associated with the inner membrane of the mitochondrion. It is a soluble protein, unlike other cytochromes, and is an essential component of the electron transfer chain. It is capable of undergoing oxidation and reduction, but does not bind oxygen. It transfers electrons between Complexes III and IV.
Cytochrome c is a highly conserved protein across the spectrum of species, found in plants, animals, and many unicellular organisms. This, along with its small size (molecular weight about 12,000 daltons), makes it useful in studies of evolutionary divergence. Its primary structure consists of a chain of 100 amino acids.
