CD19 Nano-Strep is a recombinantly expressed low affinity nanobody fused to a Twin-Strep-tag®. Nano-Streps were developed for Traceless Affinity Cell Selection (Nano-TACS®), which is based on our Strep-tag® technology. Due to their low affinity for the target, an increase in avidity is required to ensure sufficient binding to the cell surface. Combining Nano-Streps with a Strep-Tactin® backbone leads to the formation of complexes that stably bind to cells.
Depending on the Strep-Tactin® backbone, the following applications are possible:
- Fluorescent cell staining and isolation: Nano-Streps are combined with fluorophore-conjugated Strep-Tactin®.
- Affinity chromatographic cell isolation: Nano-Streps are loaded in Strep-Tactin® TACS Agarose columns.
By addition of biotin, the labeling reagents dissociate mildly and rapidly from the selected target cells in all applications, yielding minimally manipulated cells for unbiased further use.
