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 solutions be freshly made and stored in aliquots at -20 °C. The effect of storage of stock solutions should be verified for each application.
The purity of LDN-193189 is determined by HPLC analysis. The molecular is determined by mass spectrometry ([M+1]+ = 407±0.5). No acute cytotoxicity (>75% viability) is observed in mouse embryonic stem cells following a 6 hour exposure to 1 nM – 1 µM of LDN-193189.
