abstract：:A cDNA containing the full coding region of human cytochrome b5 was inserted into a vaccinia virus cDNA expression vector. Infection of human thymidine kinase-minus (TK-) 143 cells in culture with this recombinant virus resulted in production of 0.3 nmol of cytochrome b5 per mg of cell lysate protein. The expressed cy...
