Solubility: Soluble in DMSO at 100mg/ml, soluble in ethanol at 12.5mg/ml with warming, very poorly soluble in water, maximum solubility in plain water is estimated to be about 10-50uM, buffers, serum, or other additives may increase or decrease the aqueous solubility. Storage and Stability: May be stored at RT for short-term only. Long-term storage is recommended at -20C. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
