Biotin can be dissolved in dimethylformamide (DMF) at a concentration of 1.7mg/ml; 1ml of this can then added dropwise to 5ml of sodium potassium phosphate buffered saline, pH 6.8. For cell culture purposes, either HCl or NaOH may be used to titrate biotin into
solution. Biotin is stable at 100°C in moderately acid or neutral aqueous solutions; the solutions can be heat-sterilized. Solutions above pH 9 are less stable. Moderately acid and neutral solutions are stable several months.
