Research Applications

 
Progenta Acid Labile Surfactants (ALS) are novel, acid cleavable detergents that are fully compatible with mass spectrometry analysis. The Progenta ALS's have been engineered to provide a safe, robust alternative to detergents (e.g. sodium dodecyl sulfate) that are commonly used in proteomics work, but negatively impact subsequent analysis by mass spectrometry. While SDS and other detergents can improve protein solubility, they can be very difficult to remove during sample prep and purification of the protein sample. These bound detergents can cause significant impairment of protein analysis by mass spectrometry, as the surfactants can suppress analyte ion signal, promote analyte adduct formation, and present as contaminants during the analysis.

The Progenta Acid Labile Surfactants are fully mass spec compatible and alleviate the problems commonly associated with SDS and other detergents in proteomics studies. At neutral pH, the Progenta ALS functions as a powerful detergent for use in sample preparation, protein solubilization, and cell lysis protocols. After completing the experimental work, the solution is adjusted to a pH of 2.5 - 3 with trifluoroacetic acid (TFA) and incubated for 10 minutes to fully cleave the ALS into small organic molecules that do not exhibit surfactant activity or interfere with analysis by mass spectrometry. Other commercially available acid labile surfactants require incubation in harsher acidic environments of pH 1.0 to 2.0 for up to several hours and may produce an oily pellet or film from the cleavage by-products. Progenta ALS have been specially engineered to provide powerful surfactant performance with the added benefit of quick, simple acid-based detergent cleavage and removal for reproducible results in mass spectrometry-based proteomics studies.
