IMC-EB10
Based on 1 Customer Validation
IMC-EB10 (LY3012218) is an anti-FLT3 monoclonal antibody. IMC-EB10 binds to FLT3 with high affinity (Kd = 158 pM) and blocks the binding of FLT3 ligand to FLT3 (IC50 ≈ 10 nM), thereby inhibiting MAPK, STAT5, and PI3K/Akt signaling in leukemia cells. IMC-EB10 can enhance the anti-leukemic effect of Methotrexate (HY-14519) and inhibit leukemias expressing wild-type or ITD-mutated FLT3 receptors. IMC-EB10 prolongs the survival of acute lymphoblastic leukemia (ALL) cells and primary leukemia samples and reduces engraftment in non-obese diabetic/severe combined immunodeficiency patients. IMC-EB10 is indicated for leukemia research.

IMC-EB10 (10 μg/mL, 1 h) reduces FLT3 and phosphorylation of downstream signaling proteins STAT5, Akt, and MAPK in Hb1119 and SEM-K2 cells, but activates them in REH and RS411 cells[1].
IMC-EB10 (10 μg/mL, 1 h) activates FLT3 and downstream Akt in ALLs[1].
IMC-EB10 (0.4-200 nM, 1 h) inhibits FLT3-Fc-induced phosphorylation of wild-type FLT3 and ligand-independent constitutive phosphorylation of ITD-mutant FLT3 in EOL-1, EM3, BaF3-ITD and MV4;11 cells[4].
IMC-EB10 (0.4-200 nM, 1 h) inhibits FLT3-Fc-induced phosphorylation of MAPK, AKT and Stat5 in EOL-1, EM3, BaF3-ITD and MV4;11 cells[4].
IMC-EB10 (1.5-100 nM, 1 h) inhibits proliferation of FLT3-Fc-induced proliferation of EOL-1 and BaF3-ITD cells[4].
