Nori Feline PDGF-D ELISA Kit
$461.00 – $832.00
This ELISA kit is for quantification of PDGF-D in cat. This is a quick ELISA assay that reduces time to 50% compared to the conventional method, and the entire assay only takes 3 hours. This assay employs the quantitative sandwich enzyme immunoassay technique and uses biotin-streptavidin chemistry to improve the performance of the assays. An antibody specific for PDGF-D has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any PDGF-D present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for PDGF-D is added to the wells. Following wash to remove any unbound antibody reagent, a detection reagent is added. After intensive wash a substrate solution is added to the wells and color develops in proportion to the amount of PDGF-D bound in the initial step. The color development is stopped, and the intensity of the color is measured.

Background:
Platelet-derived growth factor D is a protein that is encoded by the PDGFD gene and is a member of the platelet-derived growth factor family.[1] The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a core motif of eight cysteines, seven of which are found in PDGF-D. This gene product only forms homodimers and, therefore, does not dimerize with the other three family members. It differs from alpha and beta members of this family in having an unusual N-terminal domain, the CUB domain. PDGF-D is a specific protease-activated ligand for the PDGF beta-receptor.[2] PDGF-D is expressed in many tissues such as kidney and eye.[3,4] PDGF-D is activated by urokinase plasminogen activator in prostate carcinoma cells.[5] Inducible PDGF-D expression by angiotensin II and hydrogen peroxide involves transcriptional regulation by Ets-1 and Sp1.[6] PDGF-D and its PDGF receptor beta (PDGFR-beta) are expressed in colorectal cancer.[7] PDGF-D overexpression is an independent predictor of platinum-based chemotherapy resistance and it may also be a potential biomarker for targeted therapy and poor prognosis.[8]
