Description

Mopso Sodium Salt CAS NO 79803-73-9 is a high-purity biochemical reagent widely used as a zwitterionic buffering agent in biological and biochemical research. Its primary value lies in its excellent buffering capacity in the physiological pH range, minimal interference with biological systems, and high solubility in aqueous solutions. This product is essential for researchers and manufacturers in the life sciences, pharmaceutical development, and diagnostic kit formulation sectors who require precise and stable pH control for sensitive enzymatic reactions, cell culture media, and protein purification processes.

Application

• Biochemical Research Buffers: Used to prepare stable, non-interfering buffers for enzyme kinetics studies, protein electrophoresis, and nucleic acid hybridization.
• Cell Culture Media: Serves as a critical pH-stabilizing component in mammalian and bacterial cell culture media formulations.
• Pharmaceutical Formulation: Employed as an excipient or buffering agent in the development and manufacturing of biologics, vaccines, and diagnostic reagents.
• Protein Purification & Chromatography: Utilized in buffer systems for ion-exchange, affinity, and size-exclusion chromatography to maintain protein stability and activity.
• Diagnostic Assays: A key ingredient in the formulation of buffers for ELISA, Western blotting, and other immunoassay techniques to ensure assay reproducibility.
• Molecular Biology: Provides optimal pH conditions for PCR, reverse transcription, and other nucleic acid amplification and modification procedures.

Quality Control

Our Mopso Sodium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for research and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing parameters such as assay, pH, absorbance, and heavy metal content. We adhere to relevant Good Manufacturing Practice (GMP) principles for the production of fine chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent absorption of water, which can affect purity and stability. Keep away from incompatible materials.
