Clones of T7 RNA polymerase with an N-terminal His-6 tag are available. (see [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=9116496&query_hl=1 He B, Rong M, Lyakhov D, Gartenstein H, Diaz G, Castagna R, McAllister WT, Durbin RK. ''Protein Expr Purif.'' '''1997''', ''9'', 142–151.]) | |||
It is highly recommended that you obtain this clone and purify your own polymerase. The prep is easy, you should obtain a large amount of polymerase with high activity from a single prep, and you will save a lot of money by not buying the polymerase. | |||
