As science and technology companies continue to make advancements in vaccine and viral vector-based gene therapy development, there is an increasing need for analytical techniques that can help assess quality parameters, especially in real-time. In a step toward increasing the speed of process development and improvement, Catalent collaborated with LumaCyte in the evaluation of its Radiance® Laser Force CytologyTM (LFC) instrument for more rapid and accurate measurement of quality attributes, such as viral titer and infectivity, and monitoring of the cell culture process, such as transfection efficiency.
