pSVA3

77273

This clone encodes the L22F mutant of DHFR that can serve as a dominant selection marker because it retains catalytic activity and also confers methotrexate (MTX) resistance at low MTX concentrations (125 nM).  Transfected cells amplify DHFR sequences.  Constructed by cloning a HindIII/SmaI fragment containing the gene into pSV2-neo from which neoR had been removed.  This plasmid was then cut with SmaI and BglII to remove 18 G nucleotides at the 3? end.  The BglII site was filled in, and ligated to the SmaI site, thereby destroying the original BglII and SmaI sites.  Removing the HindIII/SmaI fragment from the pSV2-neo removes all but the 3? 171 bp of neoR.
