Fast and accurate determination of vaccine titer during manufacturing is important for understanding the performance of a development process and for scaling each process step. Although single radial immunodiffusion (SRID) has been the most commonly used technique for vaccine titer determination, it can be time-consuming and imprecise, requiring up to three days for results. The Pall ForteBio Octet® system offers a simple and direct method for measuring vaccine–antigen–antibody binding, capable of delivering high-precision analysis in as little as three hours.…
