Description
The Arginase-1 Human ELISA Kit quantitates Hu Renin in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu Arginase-1.
Principle of the method
The Human Arginase-1 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, binding to the target on a different epitope from the capture antibody. A conjugated enzyme has been incorporated into the assay. 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.
Arginase-1 is a 35 kDa enzyme that that helps eliminate nitrogen by converting L-arginine to urea and L-ornithine which further converts to polyamine. These polyamines are important for cell proliferation and removal of toxins that arise from protein degradation. Expression is found in the liver, neutrophils, as well as myeloid derived suppressor cells (MDSC) and neural stem cells. Expression in macrophages has not been determined in humans, while in mice expression in M2 macrophages is well established. Arginase-1 may be expressed in the myeloid population in breast cancer tumors and is typically found in the majority of hepatocellular carcinomas.
