Despite its unique ability to ligate single-stranded DNA molecules, T4 RNA ligase has so far seen little use in molecular biology due to long reaction times, modest yields, and apparent inability to promote ligation of long oligodeoxyribonucleotides. We describe here a set of reaction conditions which dramatically shorten the reaction time and give reproducible 40 to 60% ligation of DNA fragments of up to 40 bases in length. These improvements open promising new fields of application to T4 RNA ligase.
