🔬 Common Scientific Applications

⚗️ Physiological-range buffering: Stable pH control ~6.8–8.2 (pKₐ ≈ 7.5 at 25 °C) for general lab assays.

🧪 Protein & enzyme kinetics: Minimal metal chelation and low reactivity make it a reliable assay buffer.

🔬 Fluorescence/imaging workflows: Low autofluorescence; good for spectroscopy and microscopy readouts.

🧲 Electrophoresis & separation: Component in running/transfer buffers; background electrolyte for CE method dev.

📈 Chromatography/mobile-phase modifier: pH stabilization in LC methods for biomolecule analysis.

💧 Sample prep & dilution: pH-steady diluent for standards, reagents, and extraction protocols.

🧷 Biomaterials & surface chemistry: Conditioning and wash buffer during coatings, conjugations, and immobilization.

🧫 In-vitro test systems: Buffer base for biochemical/biophysical models and diagnostic R&D formulations.

Notes (R&D only): HEPES shows relatively small pH drift with temperature but always adjust pH at working temperature. Protect solutions from strong light/trace metals to limit ROS formation; consult the SDS/CoA for your lot.

⚠️ Safety & Transport
