INFORMATION: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). A soluble version of CD155 has been shown to exist (4). High CD155 expression has recently been exploited to use engineered poliovirus to treat glioblastoma. (3)

Isotype:Mouse IgG1k

Specificity:Antibody ANC6A3 binds to cell surface CD155 on U-937 cells, and binds to recombinant CD155 in EIA.

Antibodies ANC6A3 and ANC2B2 (Catalog # 255-020) each bind to distict epitopes of CD155 and are suitable as a matched pair for sandwich EIA.
