- SynonymGDF-2,GDF2,BMP-9,BMP9
- SourceHuman GDF-2, Tag Free (GD2-H5211) is expressed from human 293 cells (HEK293). It contains AA Ser 320 - Arg 429 (Accession # Q9UK05-1).Predicted N-terminus: Ser 320Request for sequence
- Molecular Characterization
This protein carries no "tag".
The protein has a calculated MW of 12.1 kDa. The protein migrates as 14 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in ACN, TFA in Water. Normally trehalose is added as protectant before lyophilization.

Human GDF-2, Tag Free on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Immobilized Human GDF-2, Tag Free (Cat. No. GD2-H5211) at 1 μg/mL (100 μL/well) can bind Human ALK-1, His Tag (Cat. No. AL1-H5227) with a linear range of 2-16 ng/mL (QC tested).
- BackgroundHuman Growth and differentiation factor 2 (GDF-2), also known as Bone morphogenetic protein 9 (BMP-9), is a member of the BMP subgroup of the TGF-beta superfamily proteins that signal through heterodimeric complexes composed of type I and type II BMP receptors. GDF-2 Potent circulating inhibitor of angiogenesis. Signals through the type I activin receptor ACVRL1 but not other Alks. Signaling through SMAD1 in endothelial cells requires TGF-beta coreceptor endoglin/ENG.ALK1 is a signalling receptor for bone morphogenetic protein-9 (BMP-9) in endothelial cells (ECs). BMP-9 bound with high affinity to ALK1 and endoglin, and weakly to the type-I receptor ALK2 and to the BMP type-II receptor (BMPR-II) and activin type-II receptor (ActR-II) in transfected COS cells. Binding of BMP-9 to ALK2 was greatly facilitated when BMPR-II or ActR-II were co-expressed.
