DMF is for use as a solvent for the chromogenic substrate X-gal with our Senescence β-Galactosidase Staining Kit #9860. Dissolve 20 mg of X-gal per 1 mL DMF to prepare a 20X stock solution. Excess X-gal solution can be stored at -20°C in a light resistant container for one month. Note: Always use polypropylene plastic or glass to make and store X-gal solutions. Do not use polystyrene as it is dissolved by DMF.
Store at room temperature. This product is stable for 24 months.
N,N-dimethylformamide (DMF) is a colorless, polar organic solvent widely used as a solvent for chemical reactions. DMF is miscible with water and many other organic solvents. DMF from Cell Signaling Technology is 99.9% pure and is recommended for use as a solvent for the chromogenic substrate X-gal with our Senescence β-Galactosidase Staining Kit #9860. The convenient 10 ml size is more than enough material to dissolve the 150 mg of X-Gal supplied in a single #9860 kit.
