[Characteristics of A-type intracytoplasmic particles produced by human cells]
Abstract:
Radioimmunoprecipitation was used to analyse comparatively proteins in cytoplasmic A-type particles (CAP) and structural proteins of D-type virions in Hep-2 system of cultivated human cells. Proteins of CAP were iodinated and studied by electrophoresis in SDS-PAAG. In the preparations obtained, 60 000 (p60), 45 000, 42 000 and 20 000 dalton proteins wee detected. p60 was the main protein in CAP. It was precipitated by purified CAP antiserum rather than by antisera against structural proteins of D-type virions. It was thus demonstrated that the main structural protein of CAP Hep-2 cells contains no antigenic determinants of structural proteins of D-type oncoviruses.
