Strep-Tactin® TACS Agarose Column

Gravity flow column suitable for traceless affinity cell and exosome isolation
Quantity Unit price
From 10
Strep-Tactin® TACS Agarose columns are ready-to-use columns for cell selection or depletion via affinity chromatography. They contain agarose macrobeads coated with the streptavidin variant Strep-Tactin®. A special crosslinking permits the optimal use for cell-related approaches. 
The columns can be loaded with a protein of choice that is fused to a Twin-Strep-tag®. This can be for example an antibody or an antigen, which captures the cells inside the columns. Biotin addition causes the dissociation of strep-tagged proteins from Strep-Tactin®, leading to the elution of cells.
Alternatively, it is possible to load columns with Twin-Strep-tagged, desthiobiotinylated or biotinylated proteins (irreversible binding) for negative cell selection or depletion.
