Reliable MOPS sodium salt for finely controlled, consistent buffering in sensitive research workflows. MOPS (3-(N-morpholino)propanesulfonic acid) sodium salt—Catalog #B2015339—is a highly reliable zwitterionic buffer reagent widely used in biochemical and molecular biology applications. Provided as a 5 g biotech-grade powder, this formulation dissolves easily to produce buffers with excellent pH stability between 6.5 and 7.9, making it ideally suited for maintaining physiological pH in enzyme assays, nucleic acid reactions, protein purification protocols, and electrophoretic systems.

MOPS minimizes metal ion interactions and ultraviolet absorbance, offering clear advantages over common buffers in analytic workflows including spectrophotometry and gel electrophoresis. The high purity standard—combined with ultrapure Type I water preparation and 0.22 µm filtration—ensures low background and éviter contamination in delicate applications such as RNA analysis or protein folding assays. Use MOPS sodium salt as the foundation for precise buffer systems, maintaining pH fidelity across temperature shifts and prolonged incubations.

The room-temperature stability of this powder adds convenience for storage and inventory. Complete lot tracing supports reproducibility in RUO protocols, from high-throughput screening to method development. Whether calibrating enzyme kinetics, optimizing PCR pH conditions, or preparing buffers for ligand-binding assays, MOPS provides trusted buffering performance that builds robustness into experimental designs.

Why researchers choose this product:

  • Highly stable buffering capability between pH 6.5–7.9—perfect for physiological conditions
  • Low UV absorbance and minimal metal interaction—excellent for sensitive spectrophotometric assays
  • Biotech-grade purity with ultrapure water prep and microfiltration
  • Convenient storage at room temperature—ready to dissolve and deploy
  • Traceable batch information ensures reproducibility in RUO experimental workflows

Indication for Use:
This product is for Research Use Only (RUO). It is not intended for diagnostic, human, or therapeutic use.
