Extracts of RS 4;11 cells unstimulated (1) or stimulated with 100 ng/ml FL for 10 minutes (2-5) were resolved by SDS-PAGE on an 8% Tris-glycine gel and transferred to PVDF. The membrane was blocked with a 5% BSA-TBST buffer for one hour at room temperature, then incubated with the FLT3 [pY 955] antibody in a 3% BSA-TBST buffer at 4°C overnight, following prior incubation with: no peptide (1, 2), the non-phosphopeptide corresponding to the phosphopeptide immunogen (3), a generic phosphotyrosine-containing peptide (4), or the phosphopeptide immunogen (5). After washing, the membrane was incubated with goat F(ab’)2 anti-rabbit IgG HRP conjugate (Cat. ## ALI4404), and signals were detected using the Pierce SuperSignal™ method.
|Tested species reactivity||Human , Mouse|
|Host / Isotype||Rabbit / IgG|
|Immunogen||The antiserum was produced against a chemically synthesized phosphopeptide derived from the region of human FLT3 that contains tyrosine 955. This sequence is conserved in chimpanzee (100% homologous), cow and canine (90% homologous), and mouse (80% homologous).|
|Purification||Antigen affinity chromatography|
|Storage buffer||Dulbecco's PBS, pH 7.3, with 1mg/ml BSA, 50% glycerol|
|Contains||0.05% sodium azide|
|Tested Applications||Dilution *|
|Western Blot (WB)||Assay Dependent|

This gene encodes a class III receptor tyrosine kinase that regulates hematopoiesis. The receptor consists of an extracellular domain composed of five immunoglobulin-like domains, one transmembrane region, and a cytoplasmic kinase domain split into two parts by a kinase-insert domain. The 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.
