STORAGE:  2-8 C in the dark.

IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Flt3 (FMS-related tyrosine kinase 3) Ligand (Flt-3) is a growth factor that stimulates the growth and differentiation of early hematopoetic progenitor cells. Flt3 Ligand exerts weak biological effects and synergizes with other colony-stimulating factors to induce the proliferation and differentiation of cells of the myeloid and lymphoid lineages. Studies have suggested that Flt3 Ligand plays an important role in the development and expansion of dendritic cells and that it may influence NK cell survival. Flt-3Ltranscripts have only been found in stromal cells and T cells. It is expressed most often as a trans-membrane cell surface protein, although processing can yield a soluble, secreted isoform. Diseases associated with Flt-3L include vaccinia and aplastic anemia.
