Overview

The EasySep™ HLA Chimerism Whole Blood CD4 Positive Selection is designed to isolate CD4+ cells from fresh whole blood or buffy coat by positive selection. Desired cells are targeted with Tetrameric Antibody Complexes recognizing CD4 and dextran-coated magnetic particles. Labeled cells are separated using an EasySep™ magnet without the use of columns. Cells of interest remain in the tube while unwanted cells are poured off. The CD4 antigen is expressed on helper T cells and more weakly on monocytes and tissue macrophages.

This product replaces the EasySep™ Human Whole Blood CD4 Positive Selection Kit (Catalog #18082) for even faster cell isolations.

Data Figures

Starting with human whole blood, the CD4+CD14- cell content of the isolated fraction is typically 97.0 ± 1.8% (gated on CD45; mean ± SD using “The Big Easy” EasySep™ Magnet). In the above example, the purities of the start and final isolated fractions are 29.8% and 99.0%, respectively. NOTE: RBCs were removed from the start sample by ammonium chloride lysis prior to flow cytometry.
