一般描述
适于cDNA合成、表达谱及其他需要从超高丰度的rRNA和tRNA中分离mRNA的操作。GenElute mRNA试剂盒为从之前制备的总RNA中分离多腺苷酸化mRNA，或直接从哺乳动物细胞和组织中分离多腺苷酸化mRNA提供了方便的操作方法。直接制备mRNA时，需采用SDS/蛋白酶K降解法破碎细胞或组织，从而释放出RNA并去除RNases。这两种试剂盒均采用与1 μm聚苯乙烯微珠共价偶联的oligo dT30，通过杂交法捕获多腺苷酸化的mRNA。在杂交过程中，聚苯乙烯微珠继续保持悬浮状态，无需进行混合或振荡（这在纤维素或磁微粒方法中较为常见）。oligo(dT) 聚苯乙烯微珠（2-3步）可以采用比常用的oligo(dT) 纤维素微粒法（至少10步）更少的严格洗涤步骤，获得更纯净的mRNA，聚苯乙烯的种类是可选的。采用GenElute试剂盒时，基于mRNA的复合物在一个微量离心滤器上洗涤，然后在10 mM Tris-HCL, pH 7.5.缓冲液洗脱。通过上述任一种试剂盒制备的mRNA均适用于Northern杂交、表达阵列或芯片杂交、cDNA合成、文库构建等广泛的下游应用。
应用
纯化所得的mRNA可直接用于Northern分析、反转录、PCR、阵列标记及其他常规应用。
特点和优势
- 同时分离RNA、DNA和蛋白质的快速、方便的试剂
- 适合于各种数量规模的组织或细胞，可同时提取多份样本
- 是最高效的总RNA分离方法之一。以新鲜组织或细胞为起始材料，仅需1小时，即可完成纯化
