Product description

MHC I Streptamers® and Fab Streptamers® for fluorescent staining of antigen- or receptor-specific T cells. Low affinity Strep-tagged Fab fragments or MHC I molecules are multimerized with Strep-Tactin®, a streptavidin derivative, to generate multimers with high binding avidity. Strep-Tactin® fluorochromes are used for cell staining / FACS isolation. Upon addition of low concentrations of biotin (Vitamin H), which competes with high affinity for the binding of Strep-tag to Strep-Tactin®, staining reagents dissociate rapidly from the cell surface. This reversibility enables multiple cell stainings with different Strep-Tactin® fluorochromes.
