Product Information

• Name: n-Dodecyl-β-D-maltoside
• Synonyms: Lauryl maltoside Lauryl-beta-D-maltoside Lauryl-beta-D-maltopyranoside
• Brand: Biosynth
• Description: Dodecyl maltoside (DDM) is a non-ionic detergent that consists of a hydrophilic maltose head and a hydrophobic long chain alkyl tail. It has a relatively low critical micelle concentration of 0.17 mM and is considered a gentle but powerful detergent. DDM is often the best tool for solubilising/crystallising membrane proteins. Membrane proteins usually have α-helical structures that are easily destroyed when the protein is released from its membrane environment. DDM can often preserve these structures during the solubilisation. In addition, membrane proteins can often be renatured when isolated with DDM.
