Malvern’s Zetasizer Nano light scattering particle characterization system is being used by investigators at the University of Nagasaki in a novel carbohydrate-lectin binding-inhibition assay.

The assay was developed as part of a project to investigate the binding activity of both naturally occurring and engineered galactose-specific C-type lectins from a marine invertebrate. A paper describing the work is published in Biochimica et Biophysica Acta (BBA)-General Subjects, Vol 1760, Issue 3, Mar 06, pp318-325.

The outcome of the research suggests that the engineered lectin offers a convenient model for further structural and mutational studies of the carbohydrate recognition mechanism. Light scattering was used to confirm the affinity for different carbohydrates and to successfully determine agglutination rates of liposomes binding to lectins. The findings were supported by mass spectroscopy, circular dichroism and X-ray crystallography studies.

The Zetasizer Nano is now the most widely used light scattering system for the size measurement of particles and molecules. It is designed specifically to meet the low sample volume and high sensitivity requirements essential for protein characterization.

Easy to use and measuring molecules as small as 0.3 nm hydrodynamic radius, the Zetasizer offers the high sensitivity required for the measurement of solutions of proteins. Furthermore, size trends as a function of pH or additive concentration, for example, can be automated by coupling it to the MPT-2 autotitrator.

ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Assay AssemblyAssay Assembly is technique used in drug discovery to develop assays to test the cytotoxicity, genotoxicity, or other activities of a compound on a cell. Assay assembly requires chip assembly, a delivery system and a detection and analysis method. Beneficial features of assay kits or automated systems include high-throughput, high speed and sensitivity and low signal to noise ratio.NanotechnologyNanotechnology, or nanotech, is an engineering technique using molecular scale functional systems. Applications of nanotechnology include medicine and medical devices, electronics, air and water purification, food science and energy production.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. 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.
