Mouse Osteoactivin/GPNMB ELISA Kit - 1 Kit (96 Wells)Our Mouse Osteoactivin/GPNMB ELISA Kit is a sandwich ELISA intended for the quantitative determination of mouse Osteoactivin in cell culture supernates, serum and plasma (heparin, EDTA).
Transmembrane glycoprotein NMB is a protein that is encoded by the GPNMB gene. In osteoblast progenitor cells, GPNMB works as a positive regulator of osteoblast differentiation during later stages of matrix maturation and mineralization that is mediated at least in part by BMP-2 in a SMAD1 dependent manner to promote osteoblast differentiation. GPNMB can enhance the repairing process in bone fracture, demonstrated by its high expression during chondrogenesis(soft callus) and osteogenesis(hard callus) compared to the intact femurs that is why Osteoactivin(OA) could be a novel therapeutic agent used to treat generalized osteoporosis or localized osteopenia during fracture repair by stimulating bone growth and regeneration. Similarly, GPNMB expression increases during osteoclast differentiation and it is functionally implicated in this process, possibly by promoting the fusion of osteoclast progenitor cells.
