StemSpan Myeloid Exp Supplement II 100X

This defined, 100X concentrated supplement from STEMCELL Technologies is formulated for the ex vivo expansion of human CD34+ hematopoietic stem and progenitor cells along the myeloid lineage. Intended for use alongside StemSpan SFEM II medium, the additive supports the generation of CD14+ monocytes, CD1c+ dendritic cells, and macrophages in research-grade cell culture workflows.

Provided as a 100X stock in a single vial, the supplement is added at 1 part per 99 parts basal medium. It delivers a combination of recombinant cytokines and growth factors that promote myeloid commitment and proliferation while preserving cell viability across multi-day culture protocols. Typical applications include antigen-presenting cell biology, immunology, vaccine research, and early-stage cell therapy discovery.

For best stability, the frozen vial should be stored at -20°C, protected from light, and aliquoted on first use to limit freeze-thaw cycles. Once thawed, the supplement remains active for short-term refrigerated use. StemSpan Myeloid Expansion Supplement II 100X streamlines myeloid differentiation protocols by reducing handling steps and supporting reproducible results across experimental batches.
