Abstract
A reliable assay to specifically detect CD155 in tissue sections has widespread use because CD155 is expressed widely among tumor types. Additionally, detected expression of CD 155 in glioblastoma cells is at levels commensurate with susceptibility to PVSRIPO (a poliovirus construct) infection and killing. An anti-CD155 antibody can achieve mono-specific detection of CD155 in immunoblots of tumor homogenates and immunohistochemistry of tumor formalin fixed, paraffin embedded sections. The assay can be used to determine appropriate use of PVSRIPO in oncolytic immunotherapy against cancers.
