Detailed product information

Background information

In blood the CD8 antigen is expressed on human cytotoxic T cells and on a subset of CD16
+
NK cells. The CD8 antigen acts as an accessory molecule in the recognition of MHC class I/peptide complexes by the TCR heterodimer on CD8
+
cytotoxic T cells.

Detailed separation procedure

One entire buffy coat is labeled with StraightFrom
®
Buffy Coat CD8 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 CD8
+
cells can be eluted as the positively selected cell fraction.

Downstream applications

The purified CD8
+
cells are well-suited for further flow cytometric, functional, or molecular analysis.
