Synonyms :

Fms-related tyrosine kinase 3 ligand

Description :

Flt3-Ligand is a growth factor that regulates proliferation of early hematopoietic cells. Flt3-Ligand binds to cells expressing the tyrosine kinase receptor Flt3. Flt3-Ligand, by itself does not stimulate proliferation of early hematopoietic cells, but synergizes with other CSFs and interleukins to induce growth and differentiation. Unlike SCF, Flt3-Ligand has no activity on mast cells. Multiple isoforms of Flt3-Ligand have been identified. The predominant biologically active form is anchored to the cell surface as the extracellular domain of a transmembrane protein (209 a.a.). The membrane-bound isoform can be proteolytically cleaved to generate a biologically active soluble isoform. Recombinant murine Flt3-Ligand is a soluble 18.6 kDa protein consisting of 163 amino acid residues.

Source :

E.coli

Stability :

The lyophilized protein is stable for at least 2 years from date of receipt at -20⁰C. Reconstituted Flt3-Ligand is stable for at least 3 months when stored in working aliquots with a carrier protein at -20⁰C. Avoid repeated freeze/thaw cycles.

Purity :

Greater than 98% by SDS-PAGE gel and HPLC analyses

Endotoxin Level :

Endotoxin level is less than 0.1 ng per μg (1EU/μg).

Biological Activity :

Determined by the dose-dependent stimulation of the proliferation of human AML5 cells. The expected ED₅₀ for this effect is 5.0 – 8.0 ng/ml.
