A Simplified Colorimetric Test for Poliomyelitis Virus and Antibody

Abstract

Under the particular experimental conditions developed and herein described, the production of a yellow color by dispersed HeLa cell cultures in a medium containing phenol red, is regularly prevented by un-neutralized poliomyelitis virus. Thus, a simplified method is available for titration of the poliomyelitis viruses and their type-specific antibodies.
