>Human CD155 / PVR Protein, Mouse IgG2a Fc Tag, low endotoxin
This protein carries a mouse IgG2a Fc tag at the C-terminus.
The protein has a calculated MW of 62.2 kDa. As a result of glycosylation, the protein migrates as 70-100 kDa under reducing (R) condition, and 130-160 kDa under non-reducing (NR) condition (SDS-PAGE).
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

No activity loss was observed after storage at:
Human CD155, mouse IgG2a Fc tag, low endotoxin on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
FACS assay shows that recombinant Human CD155, mouse IgG2a Fc Tag (Cat. No. CD5-H5254) can bind to 293T cell overexpressing human TIGIT. The concentration of CD155 is 1 μg/ml (Routinely tested).
FACS analysis shows that the binding of Human CD155, mouse IgG2a Fc Tag to 293T overexpressing TIGIT was inhibited by increasing concentration of neutralizing Anti-Human TIGIT MAb. The concentration of CD155 used is 1 μg/ml. The IC50 is 0.1413 μg/ml (Routinely tested).
