The Human Angiopoietin Like4 (Hu ANGPTL4) ELISA quantitates Hu ANGPTL4 in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu ANGPTL4.
Principle of the method
The Human ANGPTL4 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 intensity of this signal is directly proportional to the concentration of target present in the original specimen.
Angiopoietin-like protein 4 (ANGPTL4), is a secreted protein selectively expressed in adipose tissue, liver, and placenta1-3 that plays a variety of roles in vivo, ranging from adipogenesis to angiogenesis to carcinogenesis. The expression of ANGPTL4 is also under nutritional and hormonal control. ANGPTL4 has been observed to induce a strong pro-angiogenic response independent of vascular endothelial growth factor (VEGF), and its expression has been described in hypoxic human tissues as well as a variety of cancers, including liposarcoma, hepatocellular carcinoma, and conventional renal cell carcinoma.
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.
