MOPS

MOPS buffer (3-(N-morpholino)propanesulfonic acid) is a widely used Good’s buffer, ideal for maintaining stable, near-neutral pH in biological and biochemical applications. With a pKa of 7.20 and an effective pH range of 6.5 to 7.9, MOPS provides precise buffering for RNA electrophoresis, protein purification, and chromatography. It is also a preferred running buffer for polyacrylamide gel electrophoresis (PAGE), ensuring reliable separation and analysis of nucleic acids and proteins.

• Strong pH stability for accurate experimental conditions
• Ideal for RNA electrophoresis and gel-based separation techniques
• Minimal metal ion binding for compatibility with biological assays

MOPS buffer supports high-resolution molecular biology workflows, making it a trusted choice for researchers working with nucleic acids and proteins in electrophoresis, chromatography, and biochemical assays.
