– The TargetMol Human CD34+ Cell Isolation Kit (Negative Selection) provides superparamagnetic microbeads and employs a negative selection method to isolate CD34+ cells from human peripheral blood mononuclear cells (PBMCs). The principle involves using biotin-labeled monoclonal antibodies to mark non-target cells (non-CD34+ cells), which are then removed using streptavidin-labeled magnetic beads. This process enables the isolation of human peripheral blood CD34+ cells.
