Principle of the Assay: This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat PRCP. Standards or samples are added to the appropriate micro ELISA plate wells and bound by the specific antibody. Then a biotinylated detection antibody specific for Rat PRCP and Avidin-Horseradish Peroxidase (HRP) conjugate is added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat PRCP, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm +/- 2 nm. The OD value is proportional to the concentration of Rat PRCP. You can calculate the concentration of Rat PRCP in the samples by comparing the OD of the samples to the standard curve.
NCBI and Uniprot Product Information
Uniprot Description
PRCP: Cleaves C-terminal amino acids linked to proline in peptides such as angiotensin II, III and des-Arg9-bradykinin. This cleavage occurs at acidic pH, but enzymatic activity is retained with some substrates at neutral pH. Belongs to the peptidase S28 family.
Protein type: Protease; EC 3.4.16.2
Cellular Component: lysosome
Molecular Function: peptidase activity; carboxypeptidase activity; hydrolase activity; serine-type peptidase activity
Biological Process: plasma kallikrein-kinin cascade; negative regulation of systemic arterial blood pressure; regulation of blood vessel endothelial cell migration; angiogenesis involved in wound healing; glucose homeostasis; proteolysis
