Scientific Background
Human CD155 (Polio Virus Receptor, PVR, Necl-5) is a 70 kd type I Ig superfamily molecule (1).1 It is involved in formation of intracellular junctions between epithelial cells. Its ligands include CD226(DNAM-1), and CD96(TACTILE). CD155 expression by tumor has been shown to be upregulated by Nitric Oxide(2). High CD155 expression has recently been exploited to use engineered poliovirus to treat glioblastoma. (3)

This protein was expressed in CHO Cells cells. Mammalian expression is critical for this Fc fusion protein because it ensures proper glycosylation and tertiary folding of the extracellular immunoglobulin-like domains, preserving native receptor-binding activity.
Recombinant hCD155(PVR)-muIg has been validated for: ELISA, Flow Cytometry. It is produced as a Murine IgG Fc Fusion (muIg), making it suitable as a blocking reagent, binding standard, or functional stimulant/inhibitor in immunology assays.
Recommended storage: Store at 2 - 5°C. Freeze/Thawing is not recommended.. Formulation: 50 mM Sodium Phosphate pH 7.5, 100 mM Potassium Chloride, 150mM NaCl, 0.5% Gentamicin sulfate. Avoid repeated freeze-thaw cycles. If long-term storage is needed, aliquot upon first use.
Species reactivity includes: human. Cross-reactivity was confirmed by functional binding assays (e.g., ELISA and/or FACS) against cells or recombinant proteins from the indicated species.
Available formats include: Biotin, Unconjugated. Conjugated forms are ready-to-use without secondary detection reagents for flow cytometry. Unconjugated (purified) forms can be used with anti-Fc secondary antibodies in ELISA.
