Control of Large‐Scale Plasma Thawing for Recovery of Cryoprecipitate Factor VIII1

Abstract
Cryoprecipitation is commonly used as the primary step in the preparation of clinical factor VIII concentrates; yet recovery is usually very low. Much of this loss is due to poor temperature control. A process of continuous plasma thawing was designed to overcome this. A substantial improvement resulted, with an increase in both yield and purity of factor VIII:C of > 50% in comparison to a conventional batch thaw process.
