Optimized DNA sequence  encoding Human extracellular domain of human CD155 including a C-terminal 6His tag was expressed in HEK293 cells.

Molecular weight:

Recombinant CD155 is a monomer protein consisting of 329 amino acid residue subunits,  due to glycosylation migrates as an approximately 55-60 kDa protein on SDS-PAGE.

>95%, as determined by SDS-PAGE and HPLC

Biological Activity:
The biological activity of Human PVR was measured by the binding ability of immobilized recombinant Human CD155 (2 μg/ml ,100 μl/well ) to human DNAM1 (linear range of 1 - 32 ng/ml) in a functional ELISA assay.

Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant CD155 is supplied as a 0.2 μm filtered PBS solution,  pH7.2 .

A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

Recombinant CD155, as supplied, can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.

Avoid repeated freeze/thaw cycles.

hPVR(CD155) is a member of the immunoglobulin (Ig) superfamily, with three linked extracellular Ig-like domains followed by a membrane-spanning domain and a cytoplasmic domain. Although a physiological function for CD155 is unknown, the protein binds specifically to the extracellular matrix component vitronectin (Lange et al., 2001). Transcriptional regulation of the CD155 gene is tightly controlled.
