- for pyrophosphate hydrolysis and quantification
- as a component of extraction buffer to homogenize liver
- as a component of cell lysis buffer for western blotting
| | 使用 | Sodium Pyrophosphate Decahydrate is a tetrabasic pyrophosphate salt used in buffers. | | 使用 | Sodium pyrophosphate decahydrate is used in fusion matrix. | | 定義 | ChEBI: Sodium pyrophosphate decahydrate is a hydrate that is the decahydrate form of sodium diphosphate. It has a role as a food thickening agent, a food emulsifier and a chelator. It contains a sodium diphosphate. | | 一般的な説明 | Sodium pyrophosphate tetrabasic decahydrate functions as a sequestering, clarifying, buffering agent and water softener. It is used as an emulsifier, pH buffer and dough conditioner. Sodium pyrophosphate tetrabasic acts as a thickening agent in puddings and tartar control agent in toothpaste. | | 純化方法 | Crystallise the salt from hot H2O and dry it in air at room temperature. |
