Regarding to the answer for making a solution of Methotrexate hydrate, can we use Sodium Bicarbonate to dissolve Methotrexate hydrate for cell culture?
1 Antwort-
This product is not directly soluble in water and is tested for solubility in 1M Ammonium hydroxide at 50 mg/mL. This material is also soluble in 1M Sodium hydroxide. Alternatively, anhydrous DMSO may also be used to dissolve this material at 90 mg/ml. An identical Methotrexate hydrate product, A6770, has a datasheet posted to the website. This datasheet included additional information regarding general use and solution stability. Please see the link below to review this document:
