Abstract
A simplified procedure was developed for the preparation of hemopexin from Cohn fraction IV obtained from partially hemolyzed pooled samples of serum. The method is based on precipitation with rivanol, chromatography on DEAE-cellulose, and gel filtration; it permits large quantities of the material to be treated on a laboratory scale. The preparation of heme-rich hemopexin obtained was characterized by amino acid analysis and the following N-terminal amino acid sequence: Thr-Pro-Leu-Pro-Arg-Gly-Ser-Ala-His-Gly-Asn-Val-Ala-Glu-Gly-Glu-Thr(Thr)Thr-Asn-Pro-Asp-Val-(Gly)(Leu).
