Purification of pre - s by hbsag affinitaetbindung with polymerized serum albumin.

摘要

Recombinant pre-S-HBsAg is purified by a rapid and efficient two step chromatographic process. Yeast cells expressing recombinant pre-S-HBsAg are disrupted, the cell contents are clarified and separated by polymerized human serum albumin affinity chromatography. The pre-S-HBsAg is further purified by hydrophobic interaction chromatography using butyl agarose. This process results in pre-S-HBsAg that is greater than 90% pure.
