The company is the original manufacturer and supplier of the Strep-tag/Strep-Tactin technology, an affinity chromatography system developed for protein purification.[3] The method is based on one of the strongest non-covalent interactions in nature, which is the interaction of biotin to streptavidin. An intrinsic binding affinity of the Strep-tag towards Strep-Tactin results in a highly specific interaction, which enables the isolation and purification of sensitive proteins in a native state as wells as intact protein complexes, respectively.[4][5] The technology was patented by the Max Planck Society (former “Garching Innovations”) and later assigned to IBA.[6][7] Recently, the method was further developed to be used for cell selection from whole blood or other single cell suspensions.[8]

Products and technologies edit

Cell Selection & Expansion edit

IBA has developed an affinity chromatography system for non-magnetic isolation of peripheral blood mononuclear cells, T cells, B cells and other cells of interest. This technology is known as Fab-TACS (Traceless Affinity Cell Selection) and is based on Strep-tagged Fab fragments, which reversibly capture and release the target cells. This delivers label-free, non-activated cells suitable for immunologic or cell biological assays. The technology can be used with manual gravity flow columns as well as with the automated cell selection device FABian.[9] Isolated and purified cells are being deployed for basic research as well as diagnostic applications.[10][11] The Streptamers for cell expansion enable the controlled stimulation of T cells. They consist of non-magnetic soluble protein complexes generated by multimerization of αCD3- and αCD28 Fab-Streps with a Strep-Tactin multimer. The reversible reagents can be easily removed from the cells by the addition of biotin. This allows to regulate the extent of stimulation precisely and to study functional and label-free activated T cells.

Protein Production & Assays edit

The company exhibits a wide range of tools related to recombinant protein purification consisting of expression vectors, affinity purification and detection reagents based on its Strep-tag/Strep-Tactin system.[12][13][14][15][16]

This can be used for i.e. drug screening, diagnostic assays, immobilization and interaction studies. Due to its small size and biochemically almost inert character, the Strep-tag does not influence protein folding, secretion and function.[17][18]

The latest generation of the system is called Strep-Tactin XT. In combination with the Twin Strep-tag it binds the recombinant protein of interest with an extremely high affinity. This results in improved batch purification runs, higher yields of the expressed recombinant protein and a versatile approach for the immobilization on solid surfaces like beads, slides/arrays or microplates.

Awards & Sponsorship edit

In 2011 IBA was granted multiple local innovation awards, e.g. for its Streptamer technology, which allows reversible isolation and staining of antigen-specific T cells.[25][26] Additionally, a diagnostic test developed by IBA and Fassisi for veterinary diseases was chosen as one of the top five innovations by the county of Göttingen in 2015.[27] Furthermore, the company honors young scientists and participated in research consortia as well.[28][29][30]
