How do you dissolve biotin in water? For my suggestion, you can prepare biotin stock solution completely by dissolve in the water, then add a few drops of 5N NaOH or you can add more until the powder is completely solubilized. After that, adjust the volume with water and 0.22-micron filtrate.
Is biotin powder soluble in water? Biotin is a water-soluble B vitamin (vitamin B7) that may be found in many foods but is also administered as a dietary supplement. Biotin is a coenzyme involved in the synthesis of fatty acids, isoleucine, and valine; it also plays a role in gluconeogenesis.
How do you make a biotin stock solution? Dissolve 10 mg of biotin (Sigma-Aldrich B4639) in 200 mL of D-PBS with phenol red to prepare biotin stock. Add 0.1 n NaOH in 5-µL drops to aid in dissolving. Make 10-µL aliquots and store at −20°C.
