Description
This Rat Chordin ELISA Kit is intended for quantitative detection of rat Chordin in cell culture supernates, serum and plasma (heparin, EDTA). Strip well format. Reagents for up to 96 tests.
This rat Chordin ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for Chordin has been precoated onto 96-well plates. Standards (Expression system for standard: NSO, Immunogen sequence: T27-S948) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Chordin is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB are used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the rat Chordin amount of sample captured in plate.
The capture antibody is a monoclonal antibody from mouse, the detection antibody is a biotinylated polyclonal antibody from goat. Expression system for standard: Chordin is a bone morphogenetic protein antagonist composed of four small cysteine-rich domains, whose function is not known. In humans, the chordin peptide is encoded by the CHRD gene. It is mapped to 11q23. It dorsalizes the developing embryo by binding ventralizing TGF proteins such as bone morphogenetic proteins. It may also play a role in organogenesis. In mice, Chordin is expressed in the node but not in the anterior visceral endoderm. It has been found to be required for forebrain development. In developing mice that are deficient in both chordin and noggin, the head is nearly absent. This is significant because when only noggin is deficient there are mild defects but the head still forms. Chordin is also involved in avian gastrulation. It is expressed in the anterior cells of Koller's sickle, which form the anterior cells of the primitive streak, a key structure through which gastrulation occurs
