Virica has developed a library of Viral Sensitizers (VSE™), cell enhancers, that temporarily suppress host cellular defenses during production, boosting viral yields and quality and improving scale-up consistency. These simple additives are added during infection or transfection, leave no residues post-purification, and integrate seamlessly into processes without disruption. VSEs are broadly applicable across a wide range of cell lines and virus combinations for cell and gene therapy and vaccine production. Virica’s High Throughput Virology (HTV™) platform and Design of Experiment (DoE) workflows ensure purpose-built and optimal VSE combinations for current and emergent applications.
