Epigenetic application of ATAC-seq based on Tn5 transposase purification technology

ABSTRACT: We report a set of rapid, efficient and low-cost methods for ATAC-seq library construction and data analysis, realized large-scale and rapid sequencing. These methods can provide a reference for the study of epigenetic regulation of gene expression.

Tn5 transposase and tagmentation procedures for massively scaled sequencing projects

Project description:Massively parallel DNA sequencing of thousands of samples in a single machine-run is now possible, but the preparation of the individual sequencing libraries is expensive and time-consuming. Tagmentation-based library construction, using the Tn5 transposase, is efficient for generating sequencing libraries but currently relies on undisclosed reagents, which severely limits development of novel applications and the execution of large scale projects. Here, we present simple and robust procedures for Tn5 transposase production and optimized reaction conditions for tagmentation-based sequencing library construction. We further show how molecular crowding agents both modulate library lengths and enable efficient tagmentation from sub-picogram amounts of cDNA. Comparison of single-cell RNA-sequencing libraries generated using produced and commercial Tn5 demonstrated equal performances in terms of gene detection and library characteristics. Finally, as naked Tn5 can be annealed to any oligonucleotide of choice, for example molecular barcodes in single-cell assays or methylated oligonucleotides for bisulfite sequencing, custom Tn5 production and tagmentation enables innovation in sequencing-based applications.

Transposase assisted tagmentation of RNA/DNA hybrid duplexes

Project description:Tn5-mediated transposition of double-strand DNA has been widely utilized in various high-throughput sequencing applications. Here, we report that the Tn5 transposase is also capable of direct tagmentation of RNA/DNA hybrids in vitro. As a proof-of-concept application, we utilized this activity to replace the traditional library construction procedure of RNA sequencing, which contains many laborious and time-consuming processes. Results of Transposase assisted RNA/DNA hybrids Co-tagmEntation (termed “TRACE-seq”) are comparable to traditional RNA-seq methods in terms of detected gene number, gene body coverage, gene expression measurement, library complexity, and differential expression analysis; at the meantime, TRACE-seq enables a one-tube library construction protocol and hence is more rapid (within 6h) and convenient. We expect this tagmentation activity on RNA/DNA hybrids to have broad potentials on RNA biology and chromatin research.

Tn5 transposase-mediated library preparation of single-cell cDNAs for RNA-seq

Project description:Deep sequencing of single cell-derived genomic DNA and/or cDNAs brings novel insights into oncogenesis and embryogenesis. However, traditional library preparation for RNA-Seq requires multiple steps, including shearing the target DNA/RNA and following sequential enzymatic reactions, which result in consequent sample loss and stochastic variation at each step. Such variation may significantly affect the output from sequencing. We have found that a new technique of library preparation using hyperactive Tn5 transposase for the next-generation sequencer of Illumina's platform provided high-quality libraries from 100ng of short-length (average 700~800 bp) single-cell level cDNA. This new method reduced the number of steps in the protocol, which resulted in improved reproducibility and reduced variation among the specimens. Two methods of library preparation (sonication, tagmentation with hyperactive Tn5 transposase) were compared in the case of RNA-Seq for single-cell level cDNA. Technical triplicates were used.

Biochemical analysis of chromatin targeting by Tn5 transposase

Project description:Tn5 transposase is used as a tool for detecting nucleosome-free regions of genomic DNA in eukaryotes, but its DNA target site in chromatin has not been understood. In the present study, the well-positioned dinucleosomes were reconstituted, and the Tn5 transposase target sites were mapped in the dinucleosomes in vitro. We found that Tn5 transposase preferentially targets near the entry-exit DNA region within the nucleosome, if the linker DNA exists between two nucleosomes. This specific DNA targeting by Tn5 did not depend on the linker DNA length and DNA sequence. Tn5 transposase becomes to target the middle of the linker DNA, in addition to the entry-exit site of the nucleosome, if the linker DNA length extends to 30 base pairs. These in vitro data provide direct evidence for the Tn5 target sites in the nucleosome, resulting important information for interpretation of the Tn5-transposase-based genomics methods, which have been interpreted as linker or nucleosome-free DNA regions in genomes.
