Human B7-H5/Gi24/VISTA Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human B7-H5/Gi24/VISTA Protein is expressed from HEK293 with hFc tag at the C-Terminus.
It contains Phe33-Ala194 [Accession | Q9H7M9].

分子量大小(Molecular Weight)

The protein has a predicted MW of 44.9 kDa. Due to glycosylation, the protein migrates to 70-80 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 0.22μm 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.

产品数据(Assay Data)
Bis-Tris PAGE

Human B7-H5 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human B7-H5 is greater than 95% as determined by SEC-HPLC

ELISA Data
