Fms-like tyrosine kinase 3 ligand (Flt-3 Ligand or Flt3L) is a cytokine that is involved in the regulation of hematopoiesis. It stimulates the survival, proliferation, and differentiation of various early myeloid and lymphoid progenitor cells. Flt3L is commonly used in the differentiation of hematopoietic stem cells into dendritic cells.

Human recombinant Flt3L has a molecular weight of 17.6 kDa. This protein is animal origin-free, carrier protein-free, tag-free, and non-glycosylated to ensure a homogenous population with exceptional lot-to-lot consistency. Flt3L is suitable for the culture of reproducible and high-quality myeloid progenitors and dendritic cells.
