Animal-Free GDF-2/BMP-9 Protein, Human (His)
Based on 1 publication(s) in Google Scholar
The BMP-9/GDF-2 protein is a potent inhibitor of angiogenesis that selectively signals through AVRL1 in endothelial cells. Its signaling pathway requires the TGF-β coreceptor endoglin/ENG to effectively activate SMAD1. Animal-Free GDF-2/BMP-9 Protein, Human (His) is the recombinant human-derived animal-FreeBMP-9/GDF-2 protein, expressed by E. coli , with N-His labeled tag. This product is for cell culture use only.

Description
The BMP-9/GDF-2 protein is a potent inhibitor of angiogenesis that selectively signals through AVRL1 in endothelial cells. Its signaling pathway requires the TGF-β coreceptor endoglin/ENG to effectively activate SMAD1.

Background
BMP-9/GDF-2 Protein emerges as a potent circulating inhibitor of angiogenesis, specifically signaling through the type I activin receptor ACVRL1 while excluding other Alks. In endothelial cells, its signaling pathway involves the requirement for the TGF-beta coreceptor endoglin/ENG for efficient activation of SMAD1. Existing as a homodimer with disulfide-linked structures, BMP-9/GDF-2 is detected in extracellular fluid both as a mature homodimer and in complex with its propeptide. The protein establishes high-affinity interactions with ACVRL1, BMPR2, and ACVR2B, crucial for its signal transduction cascade. Furthermore, it forms complexes with ENG, either as a heterotetramer with a 2:2 stoichiometry or as a heteromeric complex with ENG and ACVRL1. Notably, it also interacts with the type I receptor ACVR1, contributing to the intricate regulatory network within the TGF-beta signaling pathway.

Product Properties
Lyophilized powder
Lyophilized from a solution containing 20 mM sodium citrate, 0.2 M NaCl, pH 3.5, trehalose or 20 mM sodium citrate, 0.2 M NaCl, pH 4.5.
<0.01 EU per 1 μg of the protein by the LAL method.
It is recommended to reconstitute to a concentration of 100-200 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
