General description
Sodium phosphate dibasic (NaH2PO4), also known as disodium phosphate, is a commonly used phosphate salt in biochemistry research due to its versatile properties. It is a key component in the preparation of phosphate buffer saline (PBS) and phosphate buffer, a commonly used buffer solution in many biological applications. In addition to its buffer properties, NaH2PO4 is also used as a precipitating agent to form silver orthophosphate (Ag3PO4) powders, making it a valuable tool in many laboratory settings. Disodium phosphate is also a widely used emulsifier in dairy products such as cheese and other foods.
Application
Sodium phosphate dibasic has been used:
- as a component of phosphate buffered saline (PBS)
- as a component of buffer for the preparation of cryopreservation diluent
- in the preparation of McIlvaine buffer (citrate-phosphate buffer) for toluidine blue staining
- in the preparation of the S9 mix for the Ames test, and SOS Chromotest
- in the preparation of calcium deficient hydroxyapatite (CDHA) paste during the fabrication process of the CDHA scaffold
Features and Benefits
- The BioXtra product line ensures high-quality products for consistent results.
- High level of assay ( ≥99.0%), indicating its purity.
- Powder form for easy handling and use.
