Used as a non-ionic surfactant in laboratory and industrial applications, particularly for cell lysis and protein extraction in molecular biology and biochemistry. Commonly employed in membrane protein isolation due to its ability to disrupt lipid bilayers without denaturing proteins. Also utilized in immunoassays, such as ELISA and Western blotting, to reduce non-specific binding and improve signal clarity. Its consistent composition in standard solutions ensures reproducibility in analytical methods and quality control in pharmaceutical and environmental testing. Frequently chosen for cleaning steps in diagnostic kits and labware preparation where low interference is critical.
