CriticalAppraisaloftheMTTAssayinthePresenceofRottlerin1
Rottlerin is a natural product isolated from Mallotus philippinensis. This polyphenolic compound, originally described as a selective inhibitor of PKCδ, can inhibit many other PKC-unrelated kinases and has a number of biological actions, including mitochondrial uncoupling effects. We recently found that Rottlerin inhibits the transcription factor nuclear factor κB in different cell types, causing downregulation ......閱讀全文

MTT法簡介
MTT法是一種檢測細胞存活和生長的方法。MTT為黃色化合物,是一種接受氫離子的染料,可作用于活細胞線粒體中的呼吸鏈,在琥珀酸脫氫酶和細胞色素C的作用下,外源性MT還原為水不溶性的藍紫色結晶甲瓚( Formazan)并沉積在細胞中,而死細胞無此功能。二甲基亞砜(DMSO)能溶解細胞中的甲瓚,用酶聯免疫

MTT實驗心得
MTT實驗是檢測細胞活力的實驗方法，由于細胞活力與細胞數呈正相關，因此也常常用來檢測細胞的增殖情況。MTT的原理：活細胞有琥珀酸脫氫酶，將MTT還原成棕褐色沉淀。由于一般介紹園子里已經很多，筆者將自己的心得按照實驗流程與大家交流交流。1、培養好細胞點板。養細胞沒啥好說的，如果不知道細胞如何養，那就看
