    In this study, we describe an approach that enables a highly specific, effective and fast detection of polyadenylated RNA sequences in situ at the light and electron microscopy levels. The method developed is based on the incorporation of 5-bromo-2’-deoxyuridine into the growing cDNAstrand by means of the reverse transcriptase. We have shown that unlike the previously used deoxyuridine tagged with biotin or digoxigenin,5-bromo-2‘-deoxyuridine is ‘invisible’ in the DNA–DNA duplex but easily detectable in theDNA–RNA duplex. We have also shown that the replacement of deoxythymidine by 5-bromo-2‘-deoxyuridine considerably stabilizes the growing DNA–RNA duplex, thus enabling the one-step detection of polyadenylated RNA in structurally well-preserved cells.
