A method is presented for rapid and efficient 5' end labeling with 32P of capped mRNAs, by a series of three enzymatic reactions: the blocking nucleotide of the cap structure is removed by tobacco acid pyrophosphatase, and after dephosphorylation with alkaline phosphatase the 5' end is labeled with gamma-32-P-ATP and T4 polynucleotide kinase.
本文介绍了一种通过一系列三步酶促反应,用³²P对带帽mRNA进行快速高效5'端标记的方法:帽结构的封闭核苷酸被烟草酸焦磷酸酶去除,用碱性磷酸酶去磷酸化后,5'端用γ-³²P-ATP和T4多核苷酸激酶进行标记。
