Wyatt Technology, the world leader in instrumentation for absolute macromolecular and nanoparticle characterization, announces the release of a novel method suitable for determining multiple critical quality attributes of adeno-associated virus and similar small gene vectors, in a single chromatographic run. The method is based on SEC-MALS, which combines size-exclusion chromatography for separation with multi-angle light scattering for characterization. SEC-MALS was introduced by Wyatt in 1985 and has been a mainstay of biophysical characterization of biotherapeutics such as monoclonal antibodies and virus-like particles. It utilizes Wyatt’s DAWN MALS instrument coupled to an industry-standard SEC system and offers full support for FDA 21CFR(11) compliance.
