Description

General description

Mouse and human Flt-3 ligand share ~72% homology and both demonstrate cross-species activity.

Biochem/physiol Actions

Flt-3/Flk-2 Ligand (FL, or Flt-3L) is a transmembrane glycoprotein that binds and activates the Flt-3 receptor. Expression of Flt-3 is primarily restricted among hematopoietic cells to the most primitive progenitor cells.

Physical form

Lyophilized, 0.2 μm sterile filtered, with with 0.5x PBS.

Analysis Note

The biological activity is measured by its ability to stimulate the proliferation of human AML5 cells.
