Streptamers – new MHC multimer reagents for immunotherapies

Speaker: Dr. Dirk Busch, TU Munich

March 2, 2004

1:15 pm to 2:15 pm

Balthasar-Neumann-Room, Congress Center Würzburg.

 

Dr. Dirk Busch (TU Munich) will present the new Streptamer technology, a novel multimer technology for isolation and characterization of functional, antigen-specific T-cells and its applications in immunotherapies. The technology enables for the first time a reversible, antigen-specific staining of T-cells leaving the isolated T-cells phenotypically and functionally indistinguishable from untreated cells.

The new Streptamer reagents, which are based on IBA’s Strep-tag/Strep-Tactin technology, provide the following advantages in comparison to conventional multimers:

Reversible, antigen-specific staining of T-cells, isolation and characterization of functional T-cells, high staining intensities, mild and rapid dissociation of staining reagents using biotin as well as improved viability of T-cells after isolation. Several human (HLA) and mouse (H2) MHC I-Strep alleles with e.g. viral or cancer antigens are available. To meet the needs of its customers, IBA also offers a custom service to prepare custom made MHC I-Strep reagents.

 “The Streptamer technology will most likely advance immunological research since it provides new insights into T-cell biology. Moreover Streptamer-isolated T-cells may provide new therapeutic options for treating incurable diseases including viral infections and cancers.” stated CEO  Dr. Lothar Germeroth. A recent publication by Dirk H. Busch (et al.), the inventor of the Streptamer technology, was featured in the June 2002 issue of Nature Medicine. Experiments in mice demonstrated that the Streptamer technology is capable of providing antigen-specific T-cells which can be efficiently applied in adoptive transfer protocols.
