用途:离液剂和强效变性剂;溶解细胞。用于变性裂解细胞;提取RNA和DNA;无RNA酶和DNA酶活性。TRIzol是一种新型总RNA抽提试剂,可以直接从细胞或组织中提取总RNA。其含有苯酚、异硫氰酸胍等物质,能迅速破碎细胞并抑制细胞释放出的核酸酶。
异硫氰酸胍法提取制备模板核酸此法主要用于RNA的提取.标本为组织细胞及血清等.
1.异硫氰酸胍消化液
异硫氰酸胍4mol/L
柠檬酸钠(PH7.0)25mmol/L
十二烷基肌酸钠0.5%
β-巯基乙醇0.1mol/L
2.消化方法:用50~100ul细胞悬液及血清,加等体积的异硫氰酸胍消化液振混匀后,或65℃1小时,或室温放置数分钟,然后加1/10体积的3mmol/LpH5.2的醋酸钠缓冲液,再加等体积的酚:氯仿,用力振摇约10s,10000r/min,离心5min,取上清加等体积异丙醇-20℃放置3h后,14000r/min离心15min,沉定用75%冰冷乙醇离心洗涤1~2次,真空干燥,沉淀用TE缓冲液溶解即可用于逆转录PCR扩增,或放-20℃保存。
