FloChIP's histone mark data obtained in multiplexing mode
ABSTRACT: By using FloChIP’s “sample multiplex” mode, we ChIPed in parallel 5 histone marks (H3K27ac, H3K4me3, H3K27me3, H3K4me1 and H3K9me3), going from chromatin to sequencing-ready libraries, in just one day.

Project description:By using FloChIP’s “sample multiplex” mode, we ChIPed in parallel 4 different cell dilution (100k cells, 50k cells, 5k cells, and 500 cells), going from chromatin to sequencing-ready libraries, in just one day.
Project description:The assay for transposase-accessible chromatin using sequencing (ATAC-seq) is widely used to identify regulatory regions throughout the genome. However, only a few studies have been done at the single cell level (scATAC-seq) due to technical difficulties. Here we developed a simple and robust plate-based scATAC-seq method, combining upfront bulk tagmentation with single-nuclei sorting, to investigate open chromatin regions. We applied this method on mouse splenocytes and unbiasedly revealed key regulatory regions and transcription factors that define each cell (sub)type.
Project description:Purpose: To investigate the effect of Tet1 depletion on global DNA methylation, we performed whole-genome bisulfite sequencing (WGBS). Methods: Starting with as little as 1400-5251 manually micro-dissected PGCs, we used an ultra-low input method, Tn5mC-seq. Results: We generated 945 million reads for Tet1Gt/Gt PGCs and 302 million reads for wild-type PGCs. We obtained 14-16 million CpG sites per genotype at 1.76-2.66x genome coverage, which enables a comprehensive view of genome-wide DNA methylation patterns in E13.5 PGCs. PGCs are almost completely unmethylated genome-wide. Loss of Tet1 led to a subtle increase of methylation level in various genomic elements including promoters, exons, introns and repetitive elements in Tet1Gt/Gt PGCs (p<0.01). Local analysis identified 4,337 differentially methylated regions (DMRs) between Tet1-/- PGCs and wild-type cells. These DMRs are associated with 5,261 genes, among which 271 genes also exhibited differential gene expression and enriched for the cell cycle pathway (FDR=0.02). Conclusions: This result revealed that demethylation of certain set of cell cycle genes is largely abolished in the Tet1-/- PGCs. Genome-wide methylation profiles of primordial germ cells derived from the wild type (WT) and Tet1-null female embryos at E13.5 were generated by whole genome bisulfite sequencing using Illumina Hiseq.
