Somatic Hybrid Cell Formation by Viral Genome-Free Envelopes Reassembled from Solubilized HVJ (Sendai Virus)

Abstract
An envelope fraction free of nucleocapsids was reassembled from HVJ (hemag-glutinating virus of Japan, Sendai virus) virions solubilized with Nonidet P40 (4) or alkali-emasol (16). The procedure proved to be useful in place of ultraviolet-inactivated HVJ virions for fusion of cells in the formation of somatic hybrid cells.
