General description

n-Dodecyl β-D-maltoside is a non-ionic surfactant belonging to the alkyl polyglucoside family.

Application

Non-ionic detergent for the stabilization and activation of enzymes and for membrane research.
n-Dodecyl β-D-maltoside has been used in a study to assess the effect of detergents on the thermal behavior of elastin-like polypeptides (ELP). It has also been used in a study to investigate how membrane structures will respond to detergent solubilization from amino acid sequences.

Membrane proteins are vital for biological function, and their action is governed by structural properties critically depending on their interactions with the membranes. This has motivated considerable interest in studies of membrane protein folding and unfolding. Here the structural changes
