Immunoelectrophoretic study of the host antigens of Sendai virus cultivated in different substrates (embryonated hen eggs and KB cells). Note I. Analysis of chorioallantoic membrane host antigens.

The immunoelectrophhoretic analysis of two preparations of the same virus cultivated in different substrates (Sendai/egg and Sendai/KB) demonstrate that virus envelopes contain: a) identical virus-specific antigens (but also some virus antigens with only partial immunochemical identity, or even non-identity); b) antigens incorporated by the virus from the host cell, during assembly and release. The latter differ according to the host, and some of them are only partially identical with the corresponding antigens of the host cell, which suggests that host cell glycoproteins are incorporated into the virus envelope after certain virus-induced modifications.
