| Product Name | MOPSO sodium salt buffer for protein crystallization and DNA-lipid complexes, CAS 79803-73-9 |
| Catalog No. | ATR-B-YJL-0250 |
| Description | MOPSO sodium salt (3-(N-morpholino)-2-hydroxypropanesulfonic acid sodium salt) is a buffering agent that plays an important role in biotechnology research. Highly soluble in water and easy to handle, it has a pKa of 6.9 at 25°C, making it an excellent buffer particularly within the pH range of 6.5-7.9. It does not interfere with enzymatic activity or other biochemical reactions, and its low UV absorbance and high chemical stability make it well suited for spectroscopic experiments. |
| Intended Use | For use as a biological buffer in biochemical and biotechnological research, including enzyme-mediated reactions, protein analysis, protein crystallography and studies involving complexes of DNA with cationic lipids. |
| Principle / Technology | MOPSO sodium salt helps maintain a constant pH in solution, providing stable conditions for the organisms or proteins under investigation. Its low UV absorbance minimizes background interference in spectroscopic measurements, and its chemical inertness ensures compatibility with enzymatic and biochemical reaction systems. |
| Storage Conditions | Store in a tightly closed container in a cool, dry place. |
| Package Specifications | 25 kg/drum |
| Product Form | Solid (buffer salt) |
| Key Features | Highly soluble in water, allowing easy handling during experiments pKa of 6.9 at 25°C, providing excellent buffering in the pH 6.5-7.9 range Does not interfere with enzymatic activity or other biochemical reactions Low UV absorbance and high chemical stability, ideal for spectroscopic experiments Applicable as a crystallization buffer for proteins with basic isoelectric points Improves complexation of DNA with cationic lipids |
