Determine Hydrodynamic Size of Surfactant Micelles with DelsaMax CORE
27 Nov 2014Understanding the experimental properties and thermodynamics of detergent solutions is important for the cleaning industry, basic encapsulation research, and increasingly, in protein studies. This application note demonstrates how the DelsaMax CORE accurately determined the hydrodynamic size of Sodium Dodecyl Sulfate micelles, a representative surfactant. The measurements in this work all took just a few minutes thanks to the state-of-the-art dynamic light scattering detection system on the DelsaMax CORE.

Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
