一般說明
GenElute mRNA小量制备试剂盒可以简单、方便地从预先分离的总RNA中纯化多腺苷酸化mRNA。在10分钟的孵育时间内,Oligo(dT)聚苯乙烯微珠与poly(A)+ mRNA结合在一起。在微量离心滤器中洗涤以去除污染物之后,在100 mL缓冲液中洗脱poly(A)+ mRNA。在40分钟内,即可从总RNA中纯化出mRNA。
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。
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。
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。
