Recombinant Mouse FIt-3 Ligand/FLT3L (His, Flag)
Mouse Fms-related tyrosine kinase 3 ligand (Flt3 ligand or Flt3L, also known as SL cytokine and CD135L) is a single-pass type I membrane protein encoded by the Flt3lg gene. Structurally, its core domain consists of a four-helical cytokine core. As a key hematopoietic regulator, Flt3 ligand primarily functions by activating its receptor FLT3 and synergizing with other cytokines (such as GM-CSF, G-CSF, and IL-3) to stimulate the proliferation and differentiation of early hematopoietic progenitor cells, with particularly crucial roles in the development of lymphoid progenitors, natural killer cells, B cells, and dendritic cells. Consequently, this recombinant protein is widely used in cell culture research, for example, to expand hematopoietic progenitor cells or induce dendritic cells, thereby supporting studies in immunology and cancer immunotherapy.
