产品介绍

溴化十六烷基三甲胺:CTAB是一种阳离子去污剂,具有从低离子强度的溶液中沉淀核酸和酸性多聚糖的特性,在这种条件下,蛋白质和中性多聚糖仍留在溶液里,在高离子强度的溶液里,与蛋白质和大多数酸性多聚糖以外的多聚糖形成复合物,只是不能沉淀核酸。因此,CTAB可以用于从大量产生粘多糖的有机体如植物以及某些革兰氏阴性菌(包括E.coli的某些株)中制备纯化DNA 。
CTAB原理:CTAB是一种阳离子去污剂,具有从低离子强度的溶液中沉淀核酸和酸性多聚糖的特性,在这种条件下,蛋白质和中性多聚糖仍留在溶液里,在高离子强度的溶液里,能够与蛋白质和大多数酸性多聚糖以外的多聚糖形成复合物,只是不能沉淀核酸,从而将核酸分离出来。
CTAB使用方法:
1.提取DNA配方:
CTAB 4g
NaCl 16.364 g
1M Tris-HCl 20 mL( PH8.0)
冷却后0.2-1%2-巯基乙醇(400ul)氯仿-异戊醇(24:1):先加96ml氯仿,再加4ml异戊醇,摇匀即可。
2.提取RNA配方
2% CTAB(W/V)
2%聚乙烯吡咯烷酮PVP(W/V)
100 mM Tris-HCl(pH8.0,DEPC处理的水配制)
25mM EDTA
由于在高温灭菌条件下,Tris-HCl要和DEPC发生反应,所以配RNA提取缓冲液时直接用DEPC 处理的水
CTAB使用注意事项:具有刺激性,若吸入、摄入或皮肤吸收,会对人体有害。使用时要戴合适的手套和防护眼镜(或在通风橱操作)。避免吸入其粉尘。
