NADPH Tetrasodium Salt is a form of Nicotinamide Adenine Dinucleotide Phosphate (NADPH) where the sodium salt enhances its solubility, facilitating its use in various biochemical assays. In research, NADPH is a critical cofactor involved in reductive biosynthesis, antioxidant defense by regenerating reduced glutathione, and in detoxification processes within cells. It is widely used in studies of enzyme kinetics, where it serves as a reducing agent for enzymes requiring electron donation, such as those in the cytochrome P450 system. NADPH is also essential in the study of oxidative stress mechanisms, as it is a substrate for NADPH oxidase, which plays a role in the generation of reactive oxygen species. Furthermore, NADPH is used in the examination of metabolic pathways that require reduction, such as fatty acid, cholesterol, and steroid biosynthesis. The tetrasodium salt form is particularly advantageous in aqueous solutions, enabling more accurate and efficient incorporation into experimental protocols.

Dear Sir/Madam, is NADPH tetrasodium salt: sc-202725 anhydrous so that I would know how much to weigh to prepare a desired mM concentration? What are the costs of shipping the product to Poland? Any other costs? Thank you.

Asked by: michalroman
Thank you for your question. This is not anhydrous. Please contact our European Support Department for current product availability (shipping costs and lead times).

What are the storage conditions once dissolved in water (10 mM)?

Asked by: chemsd02
Thank you for your question. sc-202725 (NADPH tetrasodium salt, CAS# 2646-71-1) is stable for up to 2 months at -20°C. Avoid repeated freeze/thaw cycles. We recommend aliquotting into usable amounts first, and freezing the remaining stock. Also, avoid storing in acidic conditions.
