Sample GSM6568615 Query DataSets for GSM6568615
Status Public on Sep 09, 2022
Title ATAC_DN12_CD4_MED12
Sample type SRA
 
Source name primary T cells
Organism Homo sapiens
Characteristics treatment: unstimulated
genotype: MED12-null
chip antibody: none
Treatment protocol cells were stimulated with anti-idiotype antibody for 3 hours
Extracted molecule genomic DNA
Extraction protocol ATACseq: Approximately 100k CAR-T cells were used from each sample. Nuclei were isolated with ATAC-LB (10mM Tris-HCl pH7.4, 10mM NaCl, 3mM MgCl2, 0.1% IGEPAL) . ChIP: CAR-T cells (3 x 106) were double crosslinked by 50mM DSG (disuccinimidyl glutarate, #C1104 - ProteoChem) for 30 minutes followed by 10 minutes of 1% formaldehyde. Formaldehyde was quenched by the addition of glycine. Nuclei were isolated with ChIP lysis buffer (1% Triton x-100, 0.1% SDS, 150 mM NaCl, 1mM EDTA, and 20 mM Tris, pH 8.0). Nuclei were sheared with Covaris sonicator using the following setup: Fill level – 10, Duty Cycle – 5, PIP – 140, Cycles/Burst – 200, Time – 4 minutes). Sheared chromatin was immunoprecipitated overnight.
ATACseq libraries were prepared with Nextera DNA Library Preparation Kit (Illumina). ChIPseq libraries were prepared with Ovation Ultralow Library System V2 (Tecan).
