Organic compounds in cell culture harvests known as membrane coating components (MCC) prevent virus adsorption to membrane filters. Blending cell culture harvests with fluorocarbon removed the MCC and permitted adsorption of virus in acidified harvests to epoxy fiberglass filters. Subsequent elution with pH buffer resulted in recovery of greater than 90% of the virus with concentrations of up to 100 fold.
