| Product Name | MOPS sodium salt biological buffer for electrophoresis and protein purification, CAS 71119-22-7 |
| Catalog No. | ATR-B-YJL-0249 |
| Description | MOPS sodium salt (3-(N-morpholino)propanesulfonic acid sodium salt) is a widely used zwitterionic buffer in biochemistry and molecular biology. With a pKa of 7.2, it maintains the pH of biological samples within a narrow range close to physiological conditions, making it well suited for applications where precise pH control is essential. The compound is highly water-soluble, forms white crystals, and is easy to prepare into working solutions. |
| Intended Use | For use as a biological buffer in life science research and in vitro diagnostic applications. |
| Principle / Technology | As a Good's-type zwitterionic buffer, MOPS sodium salt resists pH changes upon addition of small amounts of acid or base. Its buffering capacity is optimal around pH 7.2, close to the physiological pH of many biological systems, and its low interference with biochemical reactions makes it compatible with a wide range of assays. |
| Storage Conditions | Store in a tightly closed container in a cool, dry place. |
| Package Specifications | 25 kg/drum |
| Product Form | White crystalline solid |
| Key Features | Strong buffering capacity with pKa of 7.2, close to physiological pH Highly soluble in water and easy to prepare Effective pH control during electrophoresis and protein purification Suitable for tissue culture experiments Used in the formulation of diagnostic kits and bioanalytical assays Component of buffer systems for a variety of biochemical experiments |
