Materials8% (w/v) paraformaldehyde stock solution: Dissolve 8 g of powdered paraformaldehyde in 100 ml water. Heat and stir (55-60 C – do not go higher). Add a few drops of 2 N sodium hydroxide until the solution clears. Make fresh each day.Alternatively, 8% paraformaldehyde can be purchased from Electron Microscopy Sciences as a custom formulation in 4 ml aliquots (cat. no. 15710-SP). Throw away ......阅读全文

TUNEL检测的原理
细胞在发生凋亡时，会激活一些DNA内切酶，这些内切酶会切断核小体间的基因组DNA。细胞凋亡时抽提DNA进行电泳检测，可以发现180-200bp的DNA ladder。基因组DNA断裂时，暴露的3’-OH可以在末端脱氧核苷酸转移酶(Terminal Deoxynucleotidyl Transfera
