TUNEL細胞凋亡檢測試劑盒(綠色螢光) | Abbkine TUNEL Apoptosis Detection Kit 貨號 KTA2010
凋亡細胞(apoptotic cells)最容易測量的特徵之一,是細胞核酸酶(cellular nucleases)破壞基因組DNA (genomic DNA)。末端脫氧核苷酸轉移酶dUTP缺口末端標記(Terminal deoxynucleotidyl transferase dUTP nick end labeling , TUNEL)是一種通過標記凋亡過程中產生的雙鏈DNA斷裂中的3′-羥基末端(3′-hydroxyl termini)來檢測DNA片段化的方法。 TUNEL測定法依賴於DNA中存在的缺口,該缺口可通過TdT進行鑑定,TdT是一種酶,可催化添加有螢光素標記的dUTP的添加。

(文獻引用出自) XI-011 induces apoptosis in lung myofibroblast in vitro. TUNEL and confocal IF microscopy were used to evaluate the effect of XI-011 on the apoptosis of bleomycin-induced myofibroblasts (A and C) or myofibroblasts derived from fibrotic lungs (B and D). Quantitative IF analysis was performed in 4 randomly selected areas. **, P < 0.01; ***, P <0.001 (ANOVA). Scale bars: 100 μm.

Background | One of the most easily measured features of apoptotic cells is the break-up of the genomic DNA by cellular nucleases. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) is a method for detecting DNA fragmentation by labeling the 3′-hydroxyl termini in the double-strand DNA breaks generated during apoptosis. The TUNEL assay relies on the presence of nicks in the DNA which can be identified by TdT, an enzyme that catalyzes the addition of dUTPs that are labeled with fluorescein. |
