| Abstract: | The activity of the interferon inducible enzyme 2'-5' oligoadenylate synthetase (2-5A synthetase, E.C. 2.7.7) which converts ATP into a series of 2'-5' oligoadenylates was measured using analytical capillary isotachophoresis. The turnover rate of ATP during the reaction was monitored by determination of its concentration at the beginning and the end of the 2-5A synthetase reaction. The enzyme was analysed in extracts of peripheral blood mononuclear cells either pretreated or not with interferon. |
