RT Journal Article SR Electronic A1 Dvořák, Zdeněk A1 Pascussi, Jean-Marc A1 Modrianský, Martin T1 Approaches to messenger RNA detection - comparison of methods JF Biomedical papers YR 2003 VO 147 IS 2 SP 131 OP 135 DO 10.5507/bp.2003.018 UL https://biomed.papers.upol.cz/artkey/bio-200302-0002.php AB Detection of messenger RNA is an important part of current biomedical research, although utilized for decades. This communication endeavors to compare three most commonly used techniques of mRNA detection, i.e. Northern blot, ribonuclease protection assay (RPA), and real-time polymerase chain reaction (RT-PCR). Principles and general procedures of these methods are described, and advantages and weaknesses of each are discussed in terms of their specificity, sensitivity, difficulty, time and material demands as well as health and environmental risks. We conclude that choice of any method discussed depends on particular purpose, experience of the researcher, and on laboratory equipment and organization.
