Zwitterionic Acid Labile Surfactant II (ZALS II), Certified Mass Spec Grade - J67721 - Alfa Aesar

J67721 Zwitterionic Acid Labile Surfactant II (ZALS II), Certified Mass Spec Grade

At neutral pH, Zwitterionic Acid Labile Surfactant II acts as a powerful detergent for use in sample preparation, protein solubilization, and cell lysis protocols. It is an alternative to CHAPS and other commonly used zwitterionic detergents used in protein analysis. When experimental solutions are adjusted to a pH of 2.5 with trifluoroacetic acid (TFA) and incubated for 30 minutes, the acid labile surfactant is fully cleaved into small organic molecules that do not exhibit surfactant activity or interfere with mass spectrometry analysis.
