Human ALK-1/ACVRL1 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human ALK-1/ACVRL1 Protein is expressed from HEK293 with His tag at the C-Terminus.
It contains Asp22-Gln118 [Accession | P37023].

分子量大小(Molecular Weight)

The protein has a predicted MW of 11.5 kDa. Due to glycosylation, the protein migrates to 25-30 kDa based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC

内毒素(Endotoxin)

Less than 1 EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Dissolve the lyophilized protein in distilled water. 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 ALK-1 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
SEC-HPLC
The purity of Human ALK-1 is greater than 95% as determined by SEC-HPLC.
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).
Cell Based Assay
Measured by its ability to inhibit BMP9 induced alkaline phosphatase production by ATDC5 mouse chondrogenic cells. The ED50 for this effect is <50 ng/mL in the presence of 2 ng/mL of recombinant human BMP9 (Cat. GDF-HM002).
背景(Background)

Activin receptor-like kinase 1 (ALK1)-mediated endothelial cell signalling in response to bone morphogenetic protein 9 (BMP9) and BMP10 is of significant importance in cardiovascular disease and cancer. Structural analyses reveal a tripartite recognition mechanism that defines BMP9 and BMP10 specificity for ALK1, and predict that crossveinless 2 is not an inhibitor of BMP9, which is confirmed by experimental evidence.
