Description
- Strep-Tactin™ Magnetic Microbeads are microspheres covalently linked to Strep-Tactin™.
- They are suitable for labeling antigen-specific cytotoxic T cells (MHC I Streptamer™) or surface marker-specific cells (Fab-TACS™/Nano-TACS™).
- To target specific cells, MHC I complexes, low affinity Fab fragments or nanobodies fused to a Twin-Strep-tag™ (MHC I-Streps, Fab-Streps or Nano-Streps) are required in addition to fluorescent Strep-Tactin™.
- Strep-Tactin™ multimerizes MHC I-Streps or Fab-/Nano-Streps, ensuring stable binding to cells.
- The resulting magnetic complexes can be used to label cells that are specific for the respective peptide-loaded MHC I molecule or for a selected surface marker.
- The addition of biotin reverses the multimerization and causes the dissociation of MHC I-Streps or Fab-/Nano-Streps from the cell surface.
- The complete removal of all labeling reagents permits serial positive selection as well as depletion steps and reserves the cells’ full biological activity.
