In Vitro

FLT3-IN-15 (compound 36) (0-100 nM) exhibits anti-proliferative activities against MOLM14 cell lines[1].
FLT3-IN-15 (0-1 μM; 72 hours) shows extremely more sensitive against MV4-11?cells than K562?cell line, and displayed good safety profiles against other cancer cell lines[1].
FLT3-IN-15 (0.01-1 μM; 4 hours) shows strongly blockage of the phosphorylation of STAT5 and Erk1/2 in MV4-11 cells[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
