Third generation Strep-tag® system

IBA’s third generation Strep-tag® system is based on the novel Strep-Tactin®XT Superflow® resin in combination with Twin-Strep-tag®. Due to a binding affinity of Strep-Tactin®XT to Twin-Strep-tag® in the low pM range, the system is superior to all other available affinity purification systems and can be used for a wide variety of approaches, e.g. protein purification and assay development.
