Cell Separation with Fab-TACS® technology - without magnetic labeling!

The fragment antigen-binding (Fab) traceless affinity cell selection (TACS) technology allows a convenient and easy way for cell separation. The desired cells can be selected directly from mouse blood, spleen, brain and lymph nodes. These cells are entirely free of microbead and antibody contamination. The positive separation of the target cells by Fab-TACS® technology is fully reversible. The purified cells are ready for in vivo use and further downstream applications.

Cell isolation with Fab-TACS® Gravity

Separating cells without magnetic or antibody labeling. The traceless affinity cell selection (Fab-TACS®) is a gentle selection process, which delivers label-free non-activated target cells of highly reproducible quality and purity directly from a variety of single cell suspensions. This process allows a multitude of downstream applications. 

Target cells are captured by cognate Fab fragments that are reversibly immobilized on a column matrix via an epitope tag. Low affinity Fab fragments are attached to a cell grade agarose matrix coated with Strep-Tactin®. Multimerization promotes the binding to target cells with high avidity. The target cells adhere to the affinity matrix. Non-target cells are washed away efficiently. Biotin triggers the elution of the target cells due to the reduced affinity of the Fab-Streps.
