一般說明
Sodium phosphate dibasic is a component in many biological buffers used in biochemical, biomedical, and molecular biological research. It is also known as disodium hydrogen phosphate (Na2HPO4), it is an inorganic salt that is highly soluble in water. It serves as a versatile buffering agent in research with a pH of 8.9 - 9.2. It is essential for making several phosphate buffers including PBS, utilized for cell culture, immunohistochemistry, Western blot, ELISA, and other applications where a stable pH is critical.
應用
Sodium phosphate dibasic may be used for phosphate buffer and Phosphate Buffered Saline (PBS) that is commonly utilized for cell culture, immunohistochemistry, western blot, and other biochemical applications where a stable pH is crucial. Including protein purification and enzymatic assays.
