StraightFrom™ LRSC CD4 MicroBead Kit, human

StraightFrom™ LRSC CD4 MicroBead Kit, human

The StraightFrom™ MicroBead Kit was developed for the rapid positive selection of CD4
+
T cells directly from one LRSC using the MultiMACS™ Cell24 Separator Plus for semi-automated separation or a MACS
®
Separator for manual separation. No sample preparation is required, including density gradient centrifugation, erythrocyte lysis, wash steps, or cell count. LS Columns and Whole Blood Column Elution Buffer are included in the kit to allow direct processing of an entire LRSC.

Background information

The CD4 antigen is expressed on T helper cells and at a lower level on monocytes and dendritic cells. The CD4 antigen is an accessory molecule in the recognition of MHC class II/peptide complexes by the TCR heterodimer on CD4
+
T helper cells.

Detailed separation procedure

One entire LRSC sample is labeled with StraightFrom™ LRSC CD4 MicroBeads and loaded onto LS 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 CD4
+
T cells can be eluted as the positively selected cell fraction.

Downstream applications

The purified CD4
+
T cells are well suited for further flow cytometric, functional, or molecular analysis.
