Measles virus nucleocapsids: large-scale purification and use in radioimmunoassays.

Journal Article (Journal Article)

Nucleocapsids in quantities approaching 1 mg were purified from 109 measles virus-infected cells. They contained one polypeptide species with a molecular weight of 59,000. Antiserum was raised in rabbits against purified nucleocapsids and used in a competitive radioimmunoassay. Because of their instability, purified nucleocapsids were not suitable for use in such an assay. Instead partially purified nucleocapsids from HEp-2 cells persistently infected with measles virus and labeled in vitro with [35S]methionine were used as the source of radioactive antigen. The radioimmunoassay thus developed measured less than 5 ng of nucleocapsids in infected cells.
