Flow cytometric analysis of U-937 (Human histiocytic lymphoma monocyte, Left) / THP-1 (Human monocytic leukemia monocyte, Right) labelling Human CD135 antibody at 1/2000 dilution (0.1 μg) / (Red) compared with a Mouse IgG1, κ (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). Goat Anti - Mouse IgG Alexa Fluor® 647 was used as the secondary antibody.
Negative control: U-937

Background
CD135, also known as FLT3 (Fms-like tyrosine kinase 3), is a class III receptor tyrosine kinase that plays a critical role in the regulation of hematopoiesis by promoting the survival, proliferation, and differentiation of hematopoietic stem and progenitor cells upon binding to its ligand FLT3L; upon activation, CD135 undergoes dimerization and trans-phosphorylation, triggering downstream signaling cascades such as RAS/MAPK and PI3K/AKT pathways, which are essential for lymphoid lineage development and dendritic cell differentiation, while mutations—especially internal tandem duplications (FLT3-ITD)—lead to constitutive kinase activity, contributing to oncogenesis, particularly in acute myeloid leukemia (AML), where it is associated with poor prognosis and targeted by specific kinase inhibitors.
