The Planova<SUP>®</SUP> filter, which was introduced into the market by Asahi Kasei Corporation at 1987, removes virus from proteins, to increase the safety of plasma products and biotech products. It blocks the virus passage by a size-exclusion mechanism, based on its unique capillary-void structure and the multi-layer filtration mechanism. The target proteins are smaller than the membrane pores, and can therefore pass through the membrane.
