Description

MOPS (3-(N-morpholino)propanesulfonic acid) is a zwitterionic buffering agent commonly used in molecular biology, biochemistry, and cell culture applications. With a buffering range centered around pH 7.0, MOPS is particularly suited for maintaining physiological pH conditions in nucleic acid manipulation workflows, protein assays, and cell-based experiments.

Proteogenixx’s MOPS Buffer Grade is produced with high purity and low levels of contaminants, ensuring dependable performance in sensitive applications such as RNA handling, electrophoresis, and enzyme-based reactions. Its strong buffering capacity and minimal interaction with metal ions or biomolecules preserve sample integrity and experimental accuracy.

MOPS is widely incorporated into biochemical buffers including MES/MOPS systems, NEBuffer formulations, and RNA electrophoresis buffers like MOPS-Formaldehyde gels. Its minimal UV absorbance and stable chemical nature make it highly suitable for spectrophotometric assays as well.

Storage: Store tightly sealed at room temperature in a dry environment to prevent degradation and moisture absorption.
