StemSpan NK Cell Diff Supp (100X)

A serum-free differentiation supplement from STEMCELL Technologies, this 100X concentrate supports the in vitro generation and expansion of natural killer (NK) cells for immunotherapy research. Added to StemSpan SFEM II or comparable hematopoietic culture medium at a 1:100 dilution, the supplement delivers a defined cytokine cocktail that drives CD34+ hematopoietic stem and progenitor cells, or peripheral blood mononuclear cells, along the NK-cell lineage. Researchers working on adoptive cell therapy, tumor immunotherapy, and immune reconstitution studies use it to generate large numbers of cytotoxic NK cells under serum-free conditions. The format is supplied as a frozen vial; aliquot upon first thaw to limit freeze-thaw cycles and store at -20°C. Each lot supports reproducible expansion, and the supplement integrates with the broader NK-cell workflow from STEMCELL Technologies, including RosetteSep isolation reagents and flow cytometry-based phenotyping panels.
