特徴

• Growth differentiation factor 2 (GDF2) also known as bone morphogenetic protein (BMP)-9 is a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. This protein regulates cartilage and bone development, angiogenesis and differentiation of cholinergic central nervous system neurons. Homozygous null mice exhibit malformations of the vasculature and skeleton.
• Sample Type:Cell culture supernates, serum, bone tissue, tissue, plasma (Heparin or EDTA).
• Intended Use:Sandwich High Sensitivity BioAssay™ ELISA kit for Quantitative Detection of Mouse BMP-9.
• Sensitivity:<10pg/ml
• Range:15.6pg/ml-1000pg/ml
• Specificity:Recognizes natural and recombinant Mouse BMP-9. There is no detectable cross-reactivity with other relevant proteins.
• Test Principle:This Mouse BMP-9 BioAssay™ ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A a monoclonal antibody from rat specific for BMP-9 has been precoated onto 96-well plates. Standards(Expression system for standard: CHO, Immunogen sequence: S319-R428) and test samples are added to the wells, a biotinylated detection a biotinylated polyclonal antibody from goat specific for BMP-9 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was 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 Mouse BMP-9 amount of sample captured in plate.
