For information regarding using immobilized metal ion affinity chromatography
(IMAC) to purify His-tagged proteins (natural or recombinant) I would recommend
a read of Volume 4 of METHODS: A companion to Methods in Enzymology. Regarding
His-tagging plasmid constructs the only commercially available ones which
come to mind are the pTrcHis and pRSET series from Invitrogen; there are likely
scads of others.
