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.

Questions about Dodecyl-beta-D-maltoside (DDM), min. 99,5 %, Ultra Quality, 250 mg, glass
What is this article?
Dodecyl-beta-D-maltoside (DDM), min. 99,5 %, Ultra Quality, 250 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Detergents & surfactants, inside Biochemicals & reagents, in Microbiologie.
A laboratory detergent or surfactant, such as SDS, Tween or Triton, solubilises membranes and stops proteins sticking. The average chain length and the peroxide content matter, especially for a protein that a peroxide would damage. A cleaning detergent for glassware is a different product.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
