蛋白别名（Synonyms）

GDF-2; GDF2; BMP-9; BMP9

种属（Species)

Human

表达系统（Source）

HEK293

表达序列（Sequence）

Ser320-Arg429

Accession

Q9UK05

标签（Tag)

No Tag

分子量（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.

内毒素（Endotoxin）

< 1 EU/μg by the LAL method.

纯度（Purity）

> 95% as determined by Bis-Tris PAGE

活性（Activity）

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 9.6ng/ml determined by ELISA.

Cell Based Assay: Measured by its ability to induce alkaline phosphatase production by ATDC5 mouse chondrogenic cells. The ED50 for this effect is 0.4-1.6 ng/mL .

制剂（Formulation）

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