Nori Human TIMP1 ELISA Kit
$461.00 – $832.00
This ELISA kit is for quantification of TIMP1 in human. 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 TIMP1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TIMP1 present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for TIMP1 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 TIMP1 bound in the initial step. The color development is stopped, and the intensity of the color is measured.

Background:
TIMP metallopeptidase inhibitor 1 ( TIMP1), a tissue inhibitor of metalloproteinases, a member of the TIMP family, is a glycoprotein that is expressed from the several tissues of organisms. The glycoprotein is a natural inhibitor of the matrix metalloproteinases (MMPs), a group of peptidases involved in degradation of the extracellular matrix. In addition to its inhibitory role against most of the known MMPs, the encoded protein is able to promote cell proliferation in a wide range of cell types, and may also have an anti-apoptotic function. Transcription of this gene is highly inducible in response to many cytokines and hormones. In addition, the expression from some but not all inactive X chromosomes suggests that this gene inactivation is polymorphic in human females. In adrenocortical cells the trophic hormone ACTH induces expression of TIMP-1 and the increase in TIMP expression is also associated with decreased collagenase activity.[1] Increased expression of TIMP1 has been found to be associated with worse prognosis of various tumors, such as laryngeal carcinoma [2] or melanoma.[3]
