ViroPrep™ AI is designed to help determine the concentration of influenza grown in chicken eggs in a shorter time than traditional approaches. ViroPrep AI is a two-step sample cleanup kit that can prepare samples taken directly from eggs for downstream analysis on the ViroCyt® 2100 Virus Counter®, providing results in hours. Understanding the total number of intact viral particles, regardless of infectivity, can facilitate informed decisions at numerous points across the vaccine development and manufacturing continuum.
