As of 6/30/2021, new and improved Strep-Tactin®XT 4Flow® products have replaced Strep-Tactin® XT Superflow® products.
Advantages of Strep-Tactin®XT 4Flow® vs. Strep-Tactin®XT Superflow®:
Strep-Tactin®XT 4Flow® high capacity is used for purification of recombinant Strep-tag®II and Twin-Strep-tag® fusion proteins under gravity flow and low pressure or FPLC.
The Strep-Tactin®XT 4Flow® high capacity resin provides 2 to 3 times higher binding capacity for Strep-tag® proteins than standard Strep-Tactin®XT 4Flow® and therefore, higher yields of highly pure Strep-tag® protein.
Dynamic binding capacity: 16 mg protein/ml resin, determined with mCherry-Twin-Strep-tag® (30kDa)
