viral antigen वाक्य

Inspired by the work of Hilary Koprowski, who developed some of the earliest monoclonal antibodies against tumour antigens and influenza viral antigens, the objective of Centocor was to commercialise monoclonal antibodies for diagnostics and therapeutics.
Virus and viral antigen are widely distributed in tissues of infected embryos and their placentas, and it is probable that microscopic lesions of necrosis and vascular damage, subsequently described for fetuses, also develop in advanced embryos.
