Efficient purification of large proteins
High affinity meets high capacity
Efficient purification of large proteins can be challenging. If the agarose has a high concentration, the more difficult it is for large proteins to enter the agarose. As a result, large target proteins are insufficiently immobilized and remain in the flow-through. The solution to this problem is highly specific Strep-Tactin®XT combined with a low concentrated agarose, Strep-Tactin®XT 4Flow®.
Strep-Tactin®XT 4Flow® is the resin to start with due to particular applicability even for low abundant or challenging proteins. In addition, a further increase in protein yield can be achieved through the high capacity variant of Strep-Tactin®XT 4Flow®.
- Higher affinity and protein yield even for large proteins
- Higher capacity for large proteins
- Broad pH stability (pH 4-10)
- Higher pressure stability compared to Strep-Tactin® Sepharose
- Cost efficient
