Related Product Information for FLT3 active protein
Background: FLT3 ligand is a receptor for the Flt3 cytokine and has a tyrosine-protein kinase activity & a growth factor that regulates proliferation of early hematopoietic cells. Flt3-Ligand synergizes with other CSFs and interleukins to induce growth and differentiation. Human flt3-Ligand (flk2-ligand) stimulates the proliferation and colony formation of certain bone marrow precursor cells including CD34+ cells.

NCBI Description

This gene encodes a class III receptor tyrosine kinase that regulates hematopoiesis. This receptor is activated by binding of the fms-related tyrosine kinase 3 ligand to the extracellular domain, which induces homodimer formation in the plasma membrane leading to autophosphorylation of the receptor. The activated receptor kinase subsequently phosphorylates and activates multiple cytoplasmic effector molecules in pathways involved in apoptosis, proliferation, and differentiation of hematopoietic cells in bone marrow. Mutations that result in the constitutive activation of this receptor result in acute myeloid leukemia and acute lymphoblastic leukemia. [provided by RefSeq, Jan 2015]

Uniprot Description

FLT3: a receptor tyrosine kinase of the PDGFR family that binds the FL cytokine. FLT3 -/- mice have an impaired developmental capacity of primitive hematopoietic progenitor cells of all lineages with the greatest impact on lymphopoietic precursors. Activating mutations found in one third of cases of acute myeloid leukemia (AML), as well as in acute lymphoblastic leukemia, acute promyelocytic leukemia and myelodysplastic syndrome. Inhibitors: Sutent and PKC412.

Product Notes

The FLT3 flt3 (Catalog #AAA844473) is an Active Protein produced from Human 293 cell expressed and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's FLT-3 Ligand can be used in a range of immunoassay formats including, but not limited to, SDS-PAGE. Researchers should empirically determine the suitability of the FLT3 flt3 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "FLT-3 Ligand, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
