절차의 가장 중요한 단계는 신선한 GST - RBD의 생성이다. 이 단계에주의하지 않으면 실패에 대한 주요 이유입니다. GST - RBD (1.2)의 세대에서 세포 lysate (2.5)와 함께 밤새 배양하기위한 모든 단계는, 하루에 수행되어야합니다. 또 다른 중요한 단계는 세포 lysates을 생산하기에 충분한 세포가있다는 것을 확실하게하는 것입니다. 세포의 낮은 수준에 존재하는 경향이 RhoC GTPase에서 볼 때 이것은 특히 중?...

rhoc gtpase activation assay

RhoC GTPase RhoA GTPase가에 91%의 상동 있습니다. 때문에 세포에 그 유행의 RhoA GTPase 많은 시약 및 기술이 개발되었습니다. 그러나, RhoC GTPase는 상대적으로 낮은 수준에서 전이성 암세포에 표시됩니다. 따라서, 몇 가지 RhoC 특정 시약이 개발되었습니다. 우리는 RhoC GTPase를 감지 Rho 활성화 분석을 적응있다. 이 기술은 활성 RhoC의 GTPase를 빼내 GST - Rho 바인딩 도메인 융합 단백질을 활용합니다. 또한, 우리는 전체의 수준 (GTP와 GDP 바운드) RhoC의 GTPase을 결정하기 위해 분석의 시작 부분에서 총 단백질을 수확 수 있습니다. 이것은 세포에 적극적으로 대 총 RhoC GTPase의 결정을 허용합니다. 이 절차의 여러 상업적인 버전은 그러나 개발되었습니다, 상업 키트 RhoA GTPase에 최적화되어 있으며, 일반적으로 RhoC GTPase를 위해 잘 작동하지 않습니다. 분석의 부품은 RhoC 특정 항체의 개발뿐만 아니라 수정되었습니다.
