Concentrate AAV8 From Small Volumes, Faster

Ultrafiltration using spin filters is a convenient approach to concentrating capsids from low starting sample volumes but should be optimized to maximize AAV yield. This head-to-head study assesses the performance of three different spin filters to concentrate AAV8. Find out which one cut processing time by ~45% and delivered the best balance of speed and yield.
