Biotinylated Human CD155/PVR Protein (Primary Amine Labeling)

产品信息(Product Info)

Recombinant Biotinylated Human CD155/PVR Protein (Primary Amine Labeling) is expressed from Expi293 with hFc tag at the C-terminal. It contains Trp21-Asn343.[Accession | P15151-1]

分子量大小(Molecular Weight)

The protein has a predicted MW of 61.8 kDa. Due to glycosylation, the protein migrates to 75-82 kDa based on Tris-Bis PAGE result.


Less than 1EU per ug by the LAL method.


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


Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.


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


-20 to -80°C for 12 months as supplied from date of receipt.
-20 to -80°C for 3-6 months in unopened state after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.

CD155 is a cell surface adhesion molecule functioning in tumor cell migration, invasion, and metastasis, and not surprisingly, is also designated as a common tumor-associated antigen. CD155 is also recognized by NK cells to induce their cytotoxicity. CD155 is also commonly referred to as the "poliovirus receptor," or PVR.
