| pubmed-article:12510000 | pubmed:abstractText | The major active form of human thrombin, alpha-thrombin, was analyzed by hydrophobic interaction high-performance liquid chromatography (HIC-HPLC). The chromatographic system included a polymeric phenyl column and elution was performed by a gradient, 2-0M sodium chloride (5-20 min). Total analysis time was 30 min per injection. By this method, a good resolution between alpha-thrombin and the proteolytically modified thrombin forms, beta- and gamma-thrombin, was obtained. In addition, the thrombin preforms, prothrombin, prethrombin 1, and prethrombin 2, were also resolved from alpha-thrombin in the system. The results from the HIC method were compared to those obtained from non-reducing sodium dodecyl sulfate-polyacrylamide gel electrophoresis. By this high-resolution chromatographic method, the rapid analysis of purified alpha-thrombin is possible. | lld:pubmed |
