Stemolecule ALK5 Inhibitor is a selective and ATP-competitive inhibitor of the TGF-β family type I receptor activin receptor-like kinase (ALK5)1. The ALK5 Inhibitor works by preventing autophosphorolation of ALK5. It has also been shown that ALK5 can replace Sox2 when reprogramming cells to induced pluripotent stem (iPS) cells. Through inhibition of the TGF-β pathway, ALK5 works to reprogram cells that have been transduced with Oct4, Klf4, and c-Myc2.

SolubilityFor a 10 mM concentrated stock solution of ALK5 Inhibitor, reconstitute the compound by adding 348 μl of DMSO to the entire contents of the vial. If precipitate is observed, warm the solution to 37°C for 2 to 5 minutes. For cell culture, the media should be prewarmed prior to adding the reconstituted compound. Note: for most cells, the maximum tolerance to DMSO is less than 0.5%. This molecule is soluble in DMSO at 100 mM and methanol at 17 mM.
Storage and StabilityStore powder at 4°C protected from light. Following reconstitution, store aliquots at -20°C. Stock solutions are stable for 6 months when stored as directed.
Quality ControlThe purity of ALK5 Inhibitor was determined by HPLC analysis. The accurate mass was determined by mass spectrometry. Cellular toxicity of ALK5 Inhibitor was tested on HeLa and HEK293 cells.
