FIG 4.
Expression and purification of Cry64Ba and Cry64Ca in HD73−. (A) Physical maps of recombinant plasmids containing cry64Ba and cry64Ca clones. (B) SDS-PAGE analysis of Cry64Ba and Cry64Ca proteins expressed in HD73− is shown. Lane 1, HD73−; lane 2, HD73− harboring pHT1A-64Ba; lane 3, HD73− harboring pHT1A-64Ca; lane 4, HD73− harboring pHT1A-64Ba/Ca (target bands are marked with an arrow); lane 5, purified Cry64Ba and Cry64Ca proteins. (C) Gel filtration chromatography of purified Cry64Ba and Cry64Ca proteins is shown. BSA (66 kDa) was used as the molecular mass standard.
