Description
Dodecyl-beta-D-maltoside (DDM) is a non-ionic alkyl maltoside detergent supplied at minimum 99,5 % in Ultra Quality for biochemistry and membrane-protein applications. It carries CAS number 69227-93-6, EG number 614-943-6, empirical formula C₂₄H₄₆O₁₁, and a molar mass of 510,63 g/mol. DDM is widely used to solubilise, stabilise, and purify integral membrane proteins while helping preserve native-like structure during extraction and chromatography. supports precise preparation of working solutions for structural biology, enzymology, and life-science workflows that depend on mild, well-characterised detergents. Offered from manufacturer Carl ROTH, this Ultra Quality grade is suited to laboratories that specify high assay detergent reagents for reproducible micelle behaviour and clean analytical backgrounds. Typical uses include protein crystallisation support, sample preparation for biophysical measurements, and formulation of lysis or reconstitution buffers where dodecyl-β-D-maltoside is the preferred maltoside surfactant.
