Fab Streptamer® is now Fab-TACS®

Our Strep-tag® technology for cell aims at minimally affecting cells during different experimental procedures. The use of low affinity Fab fragments instead of high affinity antibodies contributes to maintaining the cells‘ original state as much as possible. All our Fab-based products permit label-free cell isolation due to the reversibility of all selection reagents. This traceless affinity cell selection (Fab-TACS®) principle is the same in all our cell isolation products. This also includes our previously called Fab Streptamer products that allow cell isolation via magnetic or fluorescent labeling. Therefore we rebranded these products to Fab-TACS® products.

Magnetic T cell isolation products - magnetic Fab-TACS®

 
Magnetic Fab-TACS® consist of two components:

1) Fab-Streps (= Strep-tagged Fab fragments) which recognize the surface markers

2) Magnetic beads (= Strep-Tactin® magnetic beads) which reversibly bind the Fab-Streps

For cell isolation with Fab-Streps we offer microbeads (Strep-Tactin® magnetic microbeads) and our hand-held StrepMan permanent magnet (see below).

CD62L Fab-Strep, human lyophilized 50 µg 6-8005-150 USD 35.00
6-8005-150

CD62L Fab-Strep is a recombinantly expressed low affinity Fab fragment fused to a Twin-Strep-tag®. Due to its low affinity for the target, an increase in avidity is required to ensure sufficient binding to the cell surface. Combining Fab-Streps with a Strep-Tactin® backbone leads to the formation of complexes that stably bind to cells. ...
