摘要: Abstract Recombinant plasmids have been obtained that lead to the accumulation of five- ten-fold more puromycin- N -acetyl-transferase (PAC) mRNA and two- three-fold PAC activity than already described plasmid pSV 2 pac [Vara et al., Nucl. Acids Res. 14 (1986) 4117–4124]. When these optimized recombinants were used for stable transformation puromycin resistance, efficiencies up 1 × 10 −2 obtained, indicating -containing may be very useful dominant selectable markers gene transfer in mammalian cells.
