Bacterial mRNA purification by magnetic capture-hybridization method

Microbiol Immunol. 2004;48(2):91-6. doi: 10.1111/j.1348-0421.2004.tb03493.x.

Abstract

A magnetic capture-hybridization method was developed for purification of bacterial messenger RNA (mRNA) from total RNA by removing 5S, 16S and 23S ribosomal RNAs (rRNA). The quality of mRNA was evaluated by A(260 nm) / A(280 nm) value, denatured gel electrophoresis and RT-PCR. The results showed that highly purified and intact mRNA was obtained by this method. The magnetic capture-hybridization is a rapid and simple method for bacterial mRNA purification and has promising potential for improving studies using bacterial mRNA.
