Flt3 Ligand, Human, recombinant, Animal-derived-free

No animal-derived ingredients were used in the synthesis and purification of this cytokine product.

FMS-like tyrosine kinase 3 ligand (Flt3l) promotes the proliferation of hematopoietic progenitors in the bone marrow. Although the molecule has weak biological properties by itself, when combined with SCF or TPO it has the ability to multiply CD34+ cells in umbilical blood by several thousand times. Flt3l can also amplify myeloid colonies in combination with GM-SCF and M-CSF, as well as promote the proliferation of undifferentiated B cells in combination with IL-3, 7, and 11.
