Isolation from fetal bovine serum of a peptide similar to the alpha chain of thrombin by reversed-phase high-performance liquid chromatography.
During the preparation of erythrotropin from fetal bovine serum, a group of peptides co-eluted with this erythroid cell stimulating factor on semi-preparative reversed-phase high-performance liquid chromatography. They could be subsequently separated by a combination of reversed-phase high-performance liquid chromatography in the presence of heptafluorobutyric acid as ion-pairing reagent and gel permeation high-performance liquid chromatography. One of these peptides has been extensively purified. Partial amino acid sequence analysis indicated that fourteen of the seventeen N-terminal amino acids are identical with the N-terminal sequence of the alpha chain of bovine thrombin. The same isolation procedure could be useful for the identification of other major peptides of fetal bovine serum.
