Abstract

Цель. Серин-треониновая протеинфосфатаза 5 (PP5) является уникальным членом семейства серин-треонинових протеинфосфатаз, поскольку содержит регуляторные тетратрикопептидные повторы (TPR). PP5 активно участвует в процессах сигнальной трансдукции. Описаны процедура получения моноклональных антител, специфичных к PP5, а также особенности их использования в Вестерн-блот анализе и иммунопреципитации. Методы. Гибридомная технология применена для получения моноклональных антител. Иммунизацию проводили рекомбинантным слитым белкомGST-таг, синтезированным в бактериальной системе. Результаты. Получены специфические моноклональные антитела против РР5. Выводы. Моноклональные антитела специфично распознают рекомбинантную и эндогенную PP5 в Вестерн-блот анализе и иммунопреципитации. Они могут стать необходимым инструментом при исследовании физиологической роли PP5.
Keywords: протеинфосфатаза 5, гибридомная технология, моноклональные антитела
