    In vitro optimization of RNA-to-DNA ligation conditions. Upper panel , Ten pmols of 17-nt adenylated ssDNA oligonucleotide (Universal App DNA, CTGTAGGCACCATCAAT) was incubated with 5 pmols of a 17nt ssRNA test probe (TTTCGTTGGAAGCGGGA) in 1x NEB T4 RNA Ligase Buffer with the indicated ligase (NEB Thermostable 5’ AppDNA/RNA ligase (Therm 5' Ligase), NEB T4 Rnl2tr K227Q Ligase (trT4K) or NEB T4 Rnl2tr R55K, K227Q ligase (trT4KQ)) and/or supplements (PEG, BSA, ATP, RNaseOUT). Products were then analyzed using denaturing polyacrylamide gel electrophoresis using a combination of NEB microRNA and low range ssRNA ladders and stained with SYBR-gold. Bands were quantified and the percent product was calculated using (shifted / (total * 0.66)) to account for the molar excess of DNA over RNA. No adjustment was made to account for preferential staining of ssDNA over ssRNA. Residual signal is expected in the lower band owing to the molar excess of DNA over RNA. A high molecular weight band is visible in the Therm 5’ Ligase lane, which most likely consists of high molecular weight concatemers of the AppDNA substrate caused by incomplete 3’ blocking of these oligos or removal of the 3’ block by the Therm 5’ Ligase. This experiment was performed once.

    DNA hairpin adapter ligation. (A) DNA hairpin adapter for LOTTE-seq. The 5ʹ-end of the TGGN overhang is phosphorylated for ligation, the base-paired 3ʹ-end for blocking unwanted side reactions. RT primer binding site is indicated. (B) Adapter ligation catalysed by T4 DNA ligase, T4 RNA ligase 1 and T4 RNA ligase 2 (truncated KQ). Hairpin adapter was incubated with radioactively labelled in vitro transcribed yeast tRNA Phe with and without CCA-end. Only T4 DNA ligase fuses the tRNA with 3ʹ-CCA-end to the adapter hairpin at high selectivity, while RNA ligases 1 and 2 show considerable amounts of side reaction products with the transcript lacking a CCA-end (indicated by asterisks *). T4 RNA ligase 1 shows an additional high molecular weight product migrating in the upper part of the gel, probably resulting from the ligation of two tRNA molecules (**). The panel shows a prolonged exposure of the gels in order to visualize any unspecific ligation side reaction products. In a subsequent PCR-based amplification, such products will represent a considerable unwanted part of the sequence reads. (C) T4 DNA ligase-catalysed hairpin adapter ligation on tRNA transcripts with different 3ʹ-ends. Only the tRNA with a complete 3ʹ-CCA end was accepted for ligation, indicating a high specificity of the adapter ligation for mature tRNA 3ʹ-ends. When the tRNAs with different 3ʹ-ends were pooled, T4 DNA ligase exclusively selects the mature tRNA with CCA-end for ligation.

    Schematic workflow of the LOTTE-seq procedure. (A) A DNA hairpin-oligonucleotide (green) with a 3ʹ-TGGN overhang hybridizes to the tRNA 3ʹ-CCA end (tRNA in blue). T4 DNA ligase fuses the 3ʹ-end of the CCA terminus to the phosphorylated 5ʹ end of the adapter. (B) The tRNA is reverse transcribed with parts of the hairpin oligonucleotide serving as primer binding site. Secondary structure and modified bases can lead to premature RT stops and partial cDNA (yellow). (C) Using T4 RNA ligase I, a 5ʹ-phosphorylated and 3ʹ-blocked second adapter (red) is fused to the 3ʹ-end of the cDNA, leading to the generation of cDNA product with adapters on both sides (red and green). (D) This product is PCR-amplified with indexed primers binding to the adapter overhang sequences. (E) The cDNA library consisting of full-length as well as prematurely terminated tRNA sequences is analysed by high-throughput sequencing.

Figure not drawn to scale. ( B ) Expected sizes in bp of the RT-PCR products (amplicons) obtained from the different species of 16S rRNA ( p1 , p2 , p3 and m ) by 3′5′ RACE.

Each RNA sample was thermo-denatured (lanes b), or not (lanes a) prior to the 3′5′ ligation. The sizes (in bp) of the molecular weight markers are indicated to the left of each gel (M). ( G ) The thermodenaturation step dissociates the complementary sequences present at the 3′ and 5′ends of the p1 16S rRNA, and therefore offers to all the 16S rRNA species an equal chance to access to the T4 RNA ligase.

    Journal: PLoS ONE

    MicroRNA capture was performed with 4 different ligases using the vendor recommended protocols to compare capture efficiency across 20 different microRNA. The ligation products were analyzed by 15% denaturing urea-PAGE. Capture efficiency was determined by performing a Cy3 scan and comparing the intensities of the ∼40 nt captured microRNA band versus the ∼20 nt free microRNA band. T4 RNA Ligase 2 truncated (T4 Rnl2 T) had high average capture efficiency and low bias but many randomly sized background products. The point mutant enzymes T4 RNA Ligase 2 truncated K227Q (T4 Rnl2 TK) and T4 RNA Ligase 2 truncated KQ (T4 Rnl2 TKQ) had decreased side product formation but also lower average capture efficiency and higher bias. Thermostable 5′ App DNA/RNA Ligase (Mth Rnl), which was performed at 65°C instead of 25°C, had similar average capture efficiency and bias but with distinct ligation efficiency pattern.

    Schematic illustration of microRNA capture by 3′ adapter ligation. The 19 nt, enzymatically pre-adenlyated adapter is ligated to the 3′ OH of microRNA using T4 RNA ligase 2. The reaction is run at 25°C for 4 hours in the absence of ATP. In order to characterize capture efficiency, the microRNA is end labeled with Cy3. The 3′ end of the adapter is blocked by –ddC, a fluorophore, or other moiety to prevent the formation of concatemers and circularized products.

    Scheme of the splinted-ligation method in bRNA construction. In this method, a 2΄-5΄ linked ribo-guanosine (G)-nucleoside in an RNA strand containing the 5΄-segment and 2΄-arm (precursor 1) is transformed into a branchpoint nucleotide by ligation to an RNA strand representing the 3΄-arm (precursor 2). To do so, the two precursors are hybridized partially to a complementary RNA bridge. In this way, the 5΄-phosphate of precursor 2 is brought close to the free 3΄-hydroxyl of the 2΄-5΄ linked nucleoside of precursor 1. The two oligonucleotides are then joined by T4 RNA Ligase 2. Red, blue, and pink symbols ‘w’ represent RNA; the black line represents DNA. The 2΄-5΄ linked ribo-G-nucleoside in precursor 1 at nucleotide (nt) position 37 is highlighted. Nucleic acids downstream of a 2΄-5΄ linkage are plotted vertically in linear and branched oligonucleotides.
