🔬 Common Scientific Applications
⚗️ Near-neutral buffering: Stable pH control ~5.5–7.0 (pKₐ ≈ 6.1 at 25 °C) for general laboratory assays.
🧪 Protein & enzyme workflows: Low reactivity and minimal metal binding help reduce assay interference.
🔬 Spectroscopy/imaging friendly: Low UV absorbance and low autofluorescence for optical readouts.
🧲 Electrophoresis & separations: Component in running/transfer buffers; reliable background electrolyte.
📈 Chromatography & CE: Mobile-phase/BGE modifier to stabilize pH in LC/CE method development.
💧 Sample prep & dilution: pH-steady diluent for standards, reagents, and extraction/wash steps.
🧷 Biomaterials & surfaces: Conditioning/wash buffer during coatings, conjugations, and immobilization workflows.
🧫 In-vitro test systems: Base buffer for biochemical/biophysical models and diagnostic R&D formulations.
R&D use only. Buffer pH is temperature-dependent—adjust at the actual working temperature. MES free acid or its sodium salt may be used depending on desired ionic strength. Consult the SDS/CoA for your lot.
