Показана выраженность действия протеазы микромицета по отношению к плазмам человека и теплокровных животных, а также плазмам человека, дефицитным по определенным факторам системы гемостаза в сопоставлении с протеазами змей в реакциях с хромогенными пептидными субстратами активированного протеина C и фактора X, а также с помощью теста на активированное частичное тромбопластиновое время (АЧТВ). Были подобраны оптимальное время прединкубации протеазы микромицета А. ochraceus L-1 с плазмой крови человека (3 мин) и концентрация хромогенного пептидного субстрата активированного протеина C (от 0,1 до 0,5 мг/мл), необходимые для корректного определения протеина C.</p></abstract><trans-abstract xml:lang="en"><p>The in vitro anticoagulant action of proteases secreted by the micromycete Aspergillus ochraceus L-1 and contained in snakes’ venoms (Protac® and RVV-X® preparations) was studied.
