ProCatch His Resin is a new immobilized metal affinity chromatography (IMAC) resin to purify His-tagged recombinant proteins from prokaryotic or insect cells.
The functional moieties of this resin contain nickel to provide the proven, high-binding capacity. The proprietary chelator was developed to improve specificity, allowing a very pure protein isolation. ProCatch His Resin enables native and denaturing protein purification in a low-pressure, gravity-flow, or batch procedure. For small-scale, highly pure isolation of His-tagged proteins from mammalian cells, the μMACS™ His Isolation Kit is recommended. |

Purification of a 30 kDa histidine-tagged protein with ProCatch His Resin.
A: Marker (lane 1), lysate from cell extract (lane 2), the flow-through (lane 3) and the eluate (lane 4) were loaded onto a Coomassie-stained SDS gel.
B: Corresponding chromatogram. Proteins leaving the column were monitored by measuring absorbance at 280 nm. |
