title: [Production and purification of human interferons].
abstract: Human interferons have been classified into three types (Hu IFN-alpha, -beta, -gamma). Recently, relatively large amounts of their crude materials are being prepared using cell culture or recombinant DNA techniques. Consequently study or purification and clinical trials have been successfully performed. In this paper, the status quo and further problems on these works are reviewed.
