I would like to synthesize recombinant target protein in mammalian cell lines. Can anyone lend me a 6xHistag expression plasmid, such as pcDNA with 6xHistag.
If you already has an expression vector in hand, the easier way get your work done is to order a pair of your gene specific primers containing your cloning restriction enzyme sites and one of them containing 6xhis coding sequence (either at N-terminus, his coding sequence in 5' end primer or C-terminus, his coding sequence in 3'end primer), PCR amplify your gene, digest your PCR product with the designated R/E and ligated it into the same R/E digested vector.
