Considerations for Choosing the Right Product to Isolate Hematopoietic Progenitors

Technical tip from our dedicated team of Product and Scientific Support specialists


STEMCELL's fast, easy and column-free cell isolation products, EasySep™, RoboSep™, RosetteSep™, and SepMate™ can be used to isolate hematopoietic stem and progenitor cells (HSPCs) with high purity and recovery. Cells can be used immediately following isolation for downstream functional and biological studies.

Hematopoietic Stem Cells (HSCs) and closely related primitive progenitors in mice are distinguished from the majority of the cells in hematopoietic tissues by their lack of expression of markers specific to maturing blood cells (i.e. CD3, CD11b, CD45R/B220, GR1, TER119). In many mouse strains, HSCs are positive for SCA1 (Ly-6A/E) and cKIT (CD117) (Lin-SCA1+cKIT+phenotype) (Spangrude, Heimfeld, et al. 1988; Uchida & Weissman 1992).
