Project description:This dataset contains Xdrop followed by oxford nanopore long read sequencing performed in target tRNA gene deletion (t8) and intergenic region deletion (i50) clones in HepG2 . By applying de novo assembly based approach to Xdrop-LRS data, we identified Cas9-induced on-target genomic alteration.

Project description:Sequencing was performed to assess the ability of Nanopore direct cDNA and native RNA sequencing to characterise human transcriptomes. Total RNA was extracted from either HAP1 or HEK293 cells, and the polyA+ fraction isolated using oligodT dynabeads. Libraries were prepared using Oxford Nanopore Technologies (ONT) kits according to manufacturers instructions. Samples were then sequenced on ONT R9.4 flow cells to generate fast5 raw reads in the ONT MinKNOW software. Fast5 reads were then base-called using the ONT Albacore software to generate Fastq reads.
Project description:In this study, based on Nanopore direct RNA-seq where native RNAs are sequenced directly as near full-length transcripts in the 3' to 5' direction, transcription units of the phytopathogen Dickeya dadantii 3937 were validated and transcriptional termination sites were determined. Briefly, D. dadantii cultures were grown in M63 medium supplemented with 0.2% glucose and 0.2% PGA, until the early exponential phase (A600nm = 0.2, condition 1), or the early stationary phase (A600nm = 1.8, condition 2). RNAs were extracted using a frozen acid-phenol method, as previously described (Hommais et al. 2008), and treated successively with Roche and Biolabs DNases. Two samples were prepared: 50 µg of RNAs from each condition were pulled into one sample (sample 1), whereas the other one contained 100 µg of RNAs from condition 2 (sample 2). Both samples were then supplied to Vertis Biotechnologie AG for Nanopore native RNA-seq: total RNA preparations were first examined by capillary electrophoresis. For sample 1, ribosomal RNA molecules were depleted using an in-house developed protocol (recovery rate = 84%), whereas no ribodepletion was performed for sample 2. 3' ends of RNA were then poly(A)-tailed using poly(A) polymerase, and the Direct RNA sequencing kit (SQK-RNA002) was used to prepare the library for 1D sequencing on the Oxford Nanopore sequencing device. The direct RNA libraries were sequenced on a MinION device (MIN-101B) using standard settings. Basecalling of the fast5 files was performed using Guppy (version 3.6.1) with the following settings: --flowcell FLO-MIN106 --kit SQK-RNA002 --cpu_threads_per_caller 12--compress_fastq --reverse_sequence true --trim_strategy rna. Reads smaller than 50 nt were removed. 466 393 and 556 850 reads were generated for sample 1 and 2, respectively.
Project description:In this experiment we wanted to see how the binding behavior of the S. Cerevisiae transcription factor Leu3, on of the main regulators of leucine biosynthesis, is affected by different availability of the branched chain amino acids. For this we grow the cells in shake flask under glucose limitation and treated them 2 hours before sampling. The cells were then cross-linked with formaldehyde and ChIP-seq was performed using the Oxford Nanopore MinIon.
Project description:We present scNanoATAC-seq (Single-cell Assay for Transposase Accessible Chromatin by Oxford Nanopore Technologies Sequencing), an effective method for simultaneous detection of chromatin accessibility and genetic variation. Long fragments (about 4-5Kb) of single-cell ATAC-seq library were enriched and sequenced by Oxford Nanopore Technologies platform. Ends of long ATAC-seq fragments are regarded as chromatin accessibility signal in downstream analysis.
