Nori Sheep BMP7 ELISA Kit
$461.00 – $832.00
This ELISA kit is for quantification of BMP7 in sheep. 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 BMP7 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any BMP7 present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for BMP7 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 BMP7 bound in the initial step. The color development is stopped, and the intensity of the color is measured.

Background:
Bone morphogenetic protein 7 (BMP7, also known as osteogenic protein-1 or OP-1) is a protein that in humans is encoded by the BMP7 gene[1] and belong to BMP family and the TGF-β superfamily. Like other members of the BMP family of proteins, it plays a key role in the transformation of mesenchymal cells into bone and cartilage. It is inhibited by noggin and a similar protein, chordin, which are expressed in the Spemann-Mangold Organizer. BMP7 may be involved in bone homeostasis. It is expressed in the brain, kidneys and bladder.[2] BMP7 induces the phosphorylation of SMAD1 and SMAD5, which in turn induce transcription of numerous osteogenic genes.[3] It has been demonstrated that BMP7 treatment is sufficient to induce all of the genetic markers of osteoblast differentiation in many cell types.[2] Human recombinant BMP7 has surgical uses and is marketed under the brand name OP1. It can be used to aid in the fusion of vertebral bodies to prevent neurologic trauma.[4] Also in the treatment of tibial non-union, frequently in cases where a bone graft has failed.[5] BMP7 also has the potential for treatment of chronic kidney disease.[6][7] BMP7 administration has been proposed as a possible treatment for human infertility.[8] It was discovered that mice injected with BMP7 increased their production of “good” brown fat cells.[9]
