Overview
Using immunomagnetic positive selection, CD3+ cells are labeled with antibodies and magnetic particles, then separated without columns using an EasySep™ magnet. Unwanted cells are poured off, while desired cells remain in the tube. Bound magnetic particles are then removed from the isolated CD3+ cells, which are immediately available for downstream use. Following cell isolation with this EasySep™ Release kit, antibody complexes remain bound to the cell surface and may interact with Brilliant Violet™ antibody conjugates, polyethylene glycol-modified proteins, or other chemically related ligands. The CD3 antigen is expressed on all T cells and CD56+ NKT cells.
For even higher efficiency, the process can be automated using RoboSep™.
This kit is designed for cell therapy research applications, but may be qualified for use as an ancillary material following the framework outlined in USP<1043>. STEMCELL can work with you to qualify this reagent as an ancillary material under an approved investigational new drug (IND) or clinical trial application (CTA).

Data Figures
Starting with a single-cell suspension of human PBMCs, the CD3+ cell content of the isolated fraction is typically 98.7 ± 0.9% (mean ± SD using the purple EasySep™ Magnet). In the above example, the purities of the start and final isolated fractions are 38.4% and 99.0%, respectively.
