Development of an in Situ Enzyme Immunoassay for the Infectivity Titration of the Fast-replicating and Cytopathic Hepatitis A Virus Strain HM175A.2
註釋A simple, rapid and objective infectivity assay based on an in situ enzyme immunoassay [EIA] was development for the fast-growing and cytopathic cell culture-adapted hepatitis A virus [HAV] strain HM175A.2. The reliability of this assay was demonstrated by close agreement in virus infectivity titers in interassays and intraassays. HAV infected cell cultures after fixation could be stored for up to 1 week before testing without decline in virus titer. [Authors' abstract].
