TCAP and plague: SDS-PAGE and immunoblot analysis of lysates from ARVM infected with each adenovirus at varying multiplicities of infection (0–1000 plague-forming units/cell) for 18 or 42 h allowed selective detection of heterologously expressed telethonin with an anti-HA antibody and simultaneous detection of both endogenous and heterologously expressed telethonin with an anti-telethonin antibody (because of slower migration of the HA-tagged protein).
