Human/Cynomolgus Activin RIIA/ACVR2A Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human/Cynomolgus Activin RIIA/ACVR2A Protein is expressed from HEK293 with hFc tag at the C-terminus.
It contains Ala20-Pro135 [Accession | P27037-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of W 39.35 kDa. Due to glycosylation, the protein migrates to 55-65 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 1EU per μg by the LAL method.

制剂(Formulation)

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

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

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.

背景(Background)

Activin A receptor type 2A (ACVR2A) is a membrane receptor in the transforming growth factor- beta (TGF-β signaling pathway, which is involved in the regulation of cell proliferation, migration, and apoptosis. Loss of ACVR2A has an important role in cancer progression and distant metastasis and may serve as a prognostic marker in patients with colon cancer.

分子别名(Synonyms)

ACTR-IIA; ACTRIIA; ACVR2A; ACVR2

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
