Animal-Free BMP-9/GDF-2 Protein, Human (His)

Cat. No.: HY-P700033AF
COA Handling Instructions

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 BMP-9/GDF-2 Protein, Human (His) is the recombinant human-derived animal-FreeBMP-9/GDF-2 protein, expressed by E. coli , with N-His labeled tag. The total length of Animal-Free BMP-9/GDF-2 Protein, Human (His) is 110 a.a., with molecular weight of ~12.89 kDa.

Animal-free recombinant proteins offer high consistency and stability, whithout using or contacting of any animal-derived materials and reagents.

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. Animal-Free BMP-9/GDF-2 Protein, Human (His) is the recombinant human-derived animal-FreeBMP-9/GDF-2 protein, expressed by E. coli , with N-His labeled tag. The total length of Animal-Free BMP-9/GDF-2 Protein, Human (His) is 110 a.a., with molecular weight of ~12.89 kDa.

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
