CD4/CD62L/CD45RA Fab-TACS® Magnetic Microbead Starter Kit

Label-free isolation of central memory T cells from PBMCs


Content: 1 Stk
Fab-TACS® - Traceless Affinity Cell Selection - is a positive cell isolation approach based on our Strep-tag® technology. CD4/CD62L/CD45RA Fab-TACS® Magnetic Microbead Starter Kit allows label-free isolation of CD4+ central memory T cells (CD4+CD62L+CD45RA-) from peripheral blood mononuclear cells (PBMCs). 
Low affinity Fab fragments fused to a Twin-Strep-tag® (Fab-Streps) are incubated with Strep-Tactin® Magnetic Microbeads to form a complex that stably binds to the cell surface. After specific labeling, target cells are bound to a magnet and non-target cells efficiently washed away. In a final step, the addition of biotin causes the release of the isolated cells from magnetic microbeads. The Fab-Streps self-dissociate from the cell surface due to their low affinity. After removing biotin by washing, the isolated cells are ready for further positive selection or depletion steps or can directly be used for further downstream applications.
