Microneutralization test for determination of rhinovirus and coxsackievirus A antibody in human diploid cells.

Abstract

A method for determination of serum-neutralizing antibody titers to rhinovirus type 16 and coxsackievirus type A-4 in human diploid cells (WI-38) grown in Microtiter plates is described. A good correlation was observed when comparing neutralization tests in WI-38 and other cells. The WI-38 Microtiter method is relatively simple and economical. It is suitable for those laboratories which are required to conduct large-scale serological evaluation of antibodies for rhinoviruses and coxsackie A viruses. This system also can be used for cytomegalovirus and varicella-zoster virus, which grow relatively slowly.
