High-Purity Non-Ionic Surfactant for Protein Chemistry, Sample Prep, and Sensitive Biochemical Workflows
VWR Tween® 80, also known as Polysorbate 80, is a proteomics-grade, non-ionic surfactant used in protein solubilization, membrane disruption, and emulsification in sensitive biochemical and analytical applications. With high batch consistency, this grade is free of detectable RNase, DNase, and protease activity, ensuring compatibility with proteomics, molecular biology, and diagnostic workflows.
Tween® 80 is supplied as a viscous liquid with controlled moisture, low residue, and heavy metal content, and is ideal for use in enzyme assays, mass spectrometry sample prep, and biomolecule stabilization.
