Detailed product information

Background information

The CD3 antigen is associated with the T cell receptor (TCR) heterodimer. CD3 is expressed on all T cells, constituting 15–20% of human peripheral blood leukocytes.

Detailed separation procedure

A ½ Leukopak
®
is labeled with StraightFrom
®
Leukopak
®
CD3 MicroBeads and loaded onto Whole Blood Columns, which are placed in the magnetic field of a MultiMACS™ Cell24 Separator Plus or a MACS
®
Separator. After removing the column from the magnetic field, the magnetically retained CD3
+
cells can be eluted as the positively selected cell fraction.

Downstream applications

The purified CD3
+
cells are well suited for further flow cytometric, functional, or molecular analysis.
