title: Purification of recombinant human serum albumin efficient purification using STREAMLINE.
abstract: Two inter-related challenges must be overcome to develop a recombinant human serum albumin process. One is purity; the other is cost. Regarding cost, our goal is to produce recombinant human serum albumin at least as economically as plasma derived human serum albumin. To control production costs, maximum quantities of albumin must be produced from minimum volumes of cell culture, followed by high efficiency, high-yield purification methods. By introducing STREAMLINE technology, we have improved productivity by roughly 50% in terms of processing time and 45% in terms of yield. Furthermore, the life time of the gel and column are very long. After more than 1000 process cycles, performance remained unchanged.
