DIPLOID PORCINE EMBRYONIC CELL STRAINS, CULTURES PRODUCED THEREFROM AND USE OF SAID CULTURES FOR PRODUCTION OF VACCINES

摘要

Diploid porcine embryonic cell strain , method of growing same from porcine embryonic tissue, culturing and subculturing said diploid cell strains, and preparing a virus vacine(exemplary of the virus vaccine thus prepared is a porcine transmissible gastroenterites virus vaccine) from said diploid cell strain cultures. A novel nutrient growth medium composition for culturing and subculturing by serial subcultivation is also disclosed.
