Cell biology is reliant on the investigation of unmanipulated naturally occurring cells. State-of-the-art receptor specific isolation procedures, however, leave binding reagents on the isolated cells which is likely to induce unwanted cell modifying signalling events.

"Very efficient product to sort rare populations of T cells from human blood. Easy to use if you have a cytometer and produces clear separation of negative and positives. I highly recommend this product."

Cell biology is reliant on the investigation of unmanipulated naturally occurring cells. State-of-the-art receptor specific isolation procedures, however, leave binding reagents on the isolated cells which is likely to induce unwanted cell modifying signalling events. This can now be prevented by using a novel purification approach called Streptamer® technology. Mild purification conditions at low temperatures along with a quick and complete removal of the isolation reagents enable the isolation of quasi untouched, authentic and fully functional receptor-specific cells.

Streptamer® advantages:

• Reversible reagents (Fluorescent Streptamer® or Streptamer® Magnetic Beads) for receptor-specific isolation of naturally occurring cells with high purity

• Cells remain uncompromised due to absence of bound reagents

• Fast purification procedure at 4° C avoids signalling events or internalization

• Unique platform for save and efficient cell therapy (e.g. adoptive T-cell therapy)

• Favourable economics through standardized scalable production process


Fluorescent Streptamer®: R-Phycoerythrin (PE) (or Allophycocyanin, APC) conjugated to Strep-Tactin® for using the Streptamer® technology. Fluorescently labelled Strep-Tactin® multimerizes recombinant Strep-tagged MHC-I molecules via the reversible interaction between the Strep-tag® affinity tag and Strep-Tactin®. The resulting multimer stains T-cells which are specific for the respective peptide-loaded MHC molecule. After fluorescence assisted sorting of the cells, Strep-Tactin® can be mildly and rapidly dissociated from the T-cells by using biotin. The monomeric MHC I-Strep then spontaneously dissociates from the T-cell receptor due to its very weak binding. The rapid and complete dissociation of Streptamers from the T-cells assures full functionality of the isolated cells.

Strep-Tactin® conjugated to R-Phycoerythrin, available for 50, 150 and 500 tests. 1 test is sufficient to stain 5x106 T-cells.
