Catalog Number: 04-0036

Size: 2 mg

Alternate Name(s): 2-(3,4,6,7-tetrahydro-3-(2-methoxyphenyl)-4-oxothieno[3,2-d]pyrimidin-2-ylthio)-N-(6-methylbenzo[d]thiazol-2-yl)acetamide

Chemical Formula: C₂₃H₂₀N₄O₃S₃

Molecular Weight: 496.62

CAS Number: 686772-17-8

Purity: Greater than 96 % by HPLC analysis

Formulation: White solid

Solubility: This molecule is reported to be soluble in DMSO at 1.2 mM.

Reconstitution: For a 1.2 mM concentrated stock solution of Wnt Inhibitor IWP-4, reconstitute the compound by adding 3.36 mL 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 use in cell culture, keep the total DMSO concentration less than 0.1%.

Storage and Stability: Store powder at 4 °C protected from light. Information about the stability of Stemolecules in solution is largely not available. As a general guideline, we recommend that stock solution be freshly made and stored in aliquots at − 20 °C, protected from light. The effect of storage of stock solutions should be verified for each application.

Quality Control: The purity of Wnt Inhibitor IWP-4 was determined by HPLC analysis. The accurate mass was determined by mass spectrometry. Cellular toxicity of Wnt Inhibitor IWP-4 was tested on mouse embryonic stem cells.
