It has been shown that factor X activity determined in normal plasma using Aspergillus ochraceus protease is comparable with the activity determined with a commercial analogue, a protease from Russell’s viper venom (RVV-X®). It was revealed that the protease of A. ochraceus, along with the RVV-X® preparation, can be used to determine the content of factor X in the plasma with its reduced content. A study of the protease activity of A. ochraceus as an activator to factor X showed that it is slightly higher compared to the snake venom preparation, which can make A. ochraceus protease a promising substitute for the snake activator in diagnostics for determining the content of factor X.
