Quality attributes and extended characterization of lentiviral and gammaretroviral vectors using light scattering

Join us for a webinar on April 20, 8:00 AM PDT | 11:00 AM EDT | 17:00 CEST

Lentiviral and gammaretroviral vectors are the most popular retroviral vectors used in gene and cell therapies with more than 300 clinical trials currently underway in Phase II and Phase III. Quantifying quality attributes of these retroviral vectors is of increasing importance as they enter into the late development stages. In this webinar we demonstrate the use of two analytical techniques, batch dynamic light scattering (DLS) for rapid, low-resolution measurements and multi-angle light scattering in combination with field-flow fractionation (FFF-MALS) for extended characterization of viral vectors. We will discuss methods for evaluation of the size distribution and physical titer, impurity profiling, in-depth assessment of aggregation, and lot-to-lot variability.

Understanding Polymer Properties with Multi-Angle Light Scattering

Join us for a webinar on May 12, 8:00 AM PDT | 11:00 AM EDT | 17:00 CEST

Polymers, both of synthetic and natural origin, are an integral part of our everyday life. In contrast to low-molar-mass organic compounds, polymer samples of identical chemical composition can differ substantially by their application properties. Many important polymer properties are affected by the molar mass distribution and structural topology of the polymer chains. A multi-angle light scattering (MALS) detector following an analytical separation technique such as SEC or FFF, often in combination with an online viscometer, can provide detailed information about the molecular structure and thus proper understanding of the properties and behavior of a very wide range of polymers.
