Human GDF-2/BMP-9 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human GDF-2/BMP-9 Protein is expressed from HEK293 without tag.
It contains Ser320-Arg429 [Accession | Q9UK05].

分子量大小(Molecular Weight)

The protein has a predicted MW of 12.08 kDa. Due to glycosylation, the protein migrates to 13-15 kDa based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE

内毒素(Endotoxin)

Less than 1 EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in 4mM HCL. Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Dissolve the lyophilized protein in 4mM HCL. Please refer to the Certificate of Analysis for detailed instructions.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Bis-Tris PAGE
Human GDF-2 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
Cell Based Assay
Measured by its ability to induce alkaline phosphatase production by ATDC5 mouse chondrogenic cells. The ED50 for this effect is 0.4-4 ng/mL (QC Test).
ELISA Data
Immobilized Human GDF-2, No Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Human ALK-1, His Tag with the EC50 of 33.1ng/ml determined by ELISA (QC Test).
 
Immobilized Human GDF-2, No Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-GDF-2 Antibody, hFc Tag with the EC50 of 5.5ng/ml determined by ELISA.
SPR Data
Human/Cynomolgus Activin RIIB, hFc Tag captured on CM5 Chip via Protein A can bind Human GDF-2, No Tag with an affinity constant of 26.57 pM as determined in SPR assay (Biacore T200).
背景(Background)

Bone morphogenetic proteins (BMPs) are expressed in different cell types of the human ovarian follicle and play important roles in the regulation of ovarian function. BMP-9, also known as growth differentiation factor-2 (GDF-2), belongs to the transforming growth factor-beta (TGF-β) superfamily. BMP-9 is mainly synthesized in the liver and secreted into the blood which allows it to regulate various physiological and pathological functions.

分子别名(Synonyms)

GDF-2; GDF2; BMP-9; BMP9
