Discover the Original Strep-tag® Technology from IBA Lifesciences


At IBA Lifesciences, we're not just experts; we're the original innovators behind the Strep-tag® technology, a cornerstone in the biotechnology field for precise protein purification and analysis. Developed in 1996 from groundbreaking research at the Max-Planck-Institute, our technology has set the standard for efficiency and purity in protein isolation.

Why Choose the Original Strep-tag® System?

Strep-TactinXT twin-strep-tag protein purification

Unmatched Purity and Efficiency

Our proprietary Strep-Tactin®XT technology delivers unparalleled protein purity (>95%) through one of the strongest non-covalent interactions in nature—the binding of biotin and streptavidin. This unique approach ensures a highly selective and gentle purification process, preserving the bioactivity of proteins.
