- Streptamer® T-Cell ExpansionThe Streptamers® for T cell expansion are novel reagents for polyclonal expansion of T cells:
- They are non-magnetic soluble protein complexes generated by multimerization of αCD3- and αCD28 Fab-Streps with a Strep-Tactin® multimer.
- They are completely reversible reagents, i.e. they can be removed from the cells by the addition of biotin.
- The Streptamer® CD3/CD28 premix for T cell expansion is easy and fast with ready-to-use reagents.
- FACS Data available for the expansion of T-Cells using CD4+, CD8+, CD25 and CD 65 markers.
- Streptamer® T-Cell Isolation/Selection
Streptamers are used for efficient isolation of cells. T-Cells are separated from other cells by positive selection in a strong permanent magnetic field.
In a second step, the isolated cells are liberated from all labeling reagents by the addition of D-biotin (vitamin H) and washing in order to obtain a functional, completely label-free target cell preparation. The Fab-Strep ligands are engineered to have week affinity to the cognate cell surface receptor and the monomeric ligand therefore can be rapidly removed from its receptor by simple washing steps.

- MHC I Streptamer® Magnetic Nanobeads
The MHC I Streptamers, adducts of Strep-tagged MHC I molecules (MHC I-Streps) and Strep-Tactin®, are directed to antigen-specific CD8 T-cell receptors.
