Protein Purification Reagents and Kits
IBA LifeSciences Strep-TactinXT 4Flow resin; 50 ml
Strep-TactinXT 4Flow is a 4% agarose coupled with the streptavidin variant Strep-TactinXT and applicable for purification of Strep-tagII or Twin-Strep-tag fusion proteins. Due to the broad pH compatibility, excellent pressure stability, outstanding target purity (> 95%), and highest binding affinity, the resin is recommended for all protein classes, especially for low abundant or challenging proteins. The low concentrated agarose allows for the simple attachment of larger proteins to the stationary phase, making it particularly suitable for purification of high-molecular-weight targets. In addition, Strep-TactinXT 4Flow enables the application of denaturing agents such as urea. The suspension can be used for packing of gravity flow columns since the resin is optimized for column affinity chromatography, rather than for batch purification. To pack a column with 1 ml resin bed volume, 2 ml 50% suspension are necessary.
