Specificity / Sensitivity

FLT3 （8F2） Rabbit mAb detects endogenous levels of FLT3 protein. The antibody does not cross-react with related proteins.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the sequence surrounding Ser740 of human FLT3.

Western Blotting

Western blot analysis of extracts from Baf3/FLT3 transfected cells and SEM leukemia cells, using FLT3 （8F2） Rabbit mAb.

IHC-P （paraffin）

Immunohistochemical analysis of paraffin-embedded SEM cells, using FLT3 （8F2） Rabbit mAb.

Background

FMS-related tyrosine kinase 3 （FLT3, also called Flk2）, is a member of the type III receptor tyrosine kinase family, which includes c-Kit, PDGFR and M-CSF receptors. FLT3 is expressed on early hematopoietic progenitor cells and supports growth and differentiation within the hematopoietic system （1,2）. FLT3 is activated after binding with its ligand FL, which results in a cascade of tyrosine autophosphorylation and tyrosine phosphorylation of downstream targets （3）. The p85 subunit of PI3 kinase, SHP2, GRB2 and Shc are associated with FLT3 after FL stimulation （4-6）. Tyr589/591 is located in the juxtamembrane region of FLT3 and may play an important role in regulation of FLT3 tyrosine kinase activity. Somatic mutations of FLT3 consisting of internal tandem duplications （ITDs） occur in 20% of patients with acute myeloid leukemia （7）.
