Summary
Concentrated viral suspensions were purified by isopycnic gradients: discontinuous sucrose, continuous Percoll. With Percoll, homogenous buoyant density virus were obtained; hemagglutinating titer, concentration factor, specific activity, and reproducible yield were higher than with sucrose.
