INTRODUCTION

QC & Assay Protocol

Citation & Background

Synonym
PVR,FLJ25946,PVS,CD155,TAGE4,HVED,NECL5
Source
Mouse CD155, Mouse IgG2a Fc Tag (CD5-M5254) is expressed from human 293 cells (HEK293). It contains AA Asp 29 - Leu 348 (Accession # Q8K094-1).
Predicted N-terminus: Asp 29
Request for sequence
Molecular Characterization
This protein carries a mouse IgG2a Fc tag at the C-terminus.
The protein has a calculated MW of 61.8 kDa. The protein migrates as 35 kDa and 70-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 0.1 EU per μg by the LAL method.
Purity
>95% as determined by reduced SDS-PAGE.

Formulation
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.
Contact us for customized product form or formulation.
Reconstitution
Please see Certificate of Analysis for specific instructions.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
Storage
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
No activity loss is observed after storage at:
1. 4-8^°C for 12 months in lyophilized state;
2. -70^°C for 3 months under sterile conditions after reconstitution.

SDS-PAGE

Mouse CD155, Mouse IgG2a Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

Bioactivity

Immobilized Mouse TIGIT, His Tag (Cat. No. TIT-M52E6) at 10 μg/mL (100 μL/well) can bind Mouse CD155, mouse IgG2a Fc tag (Cat. No. CD5-M5254) with a linear range of 0.039-1.25 μg/mL (QC tested).

Background
CD155 (cluster of differentiation 155) also known as the poliovirus receptor is a protein that is encoded by the PVR gene. CD155 is a Type I transmembrane glycoprotein in the immunoglobulin superfamily. Commonly known as Poliovirus Receptor (PVR) due to its involvement in the cellular poliovirus infection in primates, CD155's normal cellular function is in the establishment of intercellular adherens junctions between epithelial cells. The role of CD155 in the immune system is unclear, though it may be involved in intestinal humoral immune responses. Subsequent data has also suggested that CD155 may also be used to positively select MHC-independent T cells in the thymus.
