Sample GSM3495117 Query DataSets for GSM3495117
Status Public on Nov 28, 2021
Title Non gustatory epithelium P0 control- Input
Sample type SRA
Source name Lingual epithelium
Organism Mus musculus
Characteristics cell type: Lingual cells
tissue: Lingual epithelium
age: Postnatal day 0
genotype: Control
chip antibody: none
Extracted molecule genomic DNA
Extraction protocol Basal lingual epithelial cells were purified from P0 newborn mice. Tongues were removed from the mandible and cut to exclude the posterior circumvallate papillae. For ChIP, only control mice were collected. Tissues were cut into small pieces and incubated with 1.26U/mL dispase (Invitrogen) and 0.3% type 1 collagenase (Worthington) for 45 minutes at 37ºC with 80 rpm shaking. Tissues were washed with 1xPBS, dissociated with 0.25% Trypsin with 2.21mM EDTA (Corning Cellgro; Manassas, VA, USA), and then washed twice with 1xPBS. Cells were stained with 1:200 EpCAM-APC antibodies (Biolegend; San Diego, CA, USA) for 30 min on ice and washed twice with 1x HBSS prior to cell sorting.
For high-throughput ChIP sequencing, libraries were constructed from 4ng of Purified DNA using the DNA SMART ChIP-Seq Kit (Clontech; Palo Alto, CA, USA) according to the manufacturer’s instructions. Constructed ChIP-seq libraries were sequenced on the Illumina NextSeq 500 platform. Two biological replicates were used for ChIP experiments.

Instrument model Illumina NextSeq 500
Data processing ChIP-seq reads were aligned to the mm10 reference genome using bowtie2 (v2.3.3, default parameters).
Duplicate reads were removed by the Samtools software v0.1.19 (Li et al. 2009).
Peaks (mostly broad) in H2AK119ub1 ChIP samples were called as previously described (Goldberg et al. 2010) for the two replicates independently.
To visualize ChIP-seq signals, we used the Integrative Genomics Viewer (IGV; and TDF files from the igvtools (v2.3.57;
