Sample GSM2255192 Query DataSets for GSM2255192
Status Public on Jul 30, 2016
Title BM1077-LMPP-Frozen-160107-91
Sample type SRA
 
Source name LMPP
Organism Homo sapiens
Characteristics cell type: lymphoid primed multipotent progenitor
doner id: BM1077
Treatment protocol NA
Extracted molecule genomic DNA
Extraction protocol Single cells were captured using the C1 Single-Cell Auto Prep IFC microfluidic chips. Cells were permeabilized and accessible fragments were captured using 20 µL of Tn5 transposition mix (1.5x TD buffer, 1.5 µL transposease (Nextera DNA Sample Prep Kit, Illumina), 1x C1 Loading Reagent with low salt (Fluidigm), and 0.15% NP40) at 30 minutes at 37°C.
In a 96-well plate, 10 µL of harvested libraries were amplified in 50 µL PCR for an additional 14 cycles (1.25 µM custom Nextera dual-index PCR primers (Supplementary Table 1) in 1x NEBnext High-Fidelity PCR Master Mix) using the following PCR conditions: 72°C for 5min; 98°C for 30 s; and thermocycling at 98°C for 10 s, 72°C for 30 s, and 72°C for 1 min. The PCR products were pooled creating a final volume of ~4.8 mL. The pooled library was purified on a single MinElute PCR purification column (Qiagen) yielding libraries at an approximate concentration of ~1 µM. Libraries were quantified using qPCR prior to sequencing.

Description Sample 283
Data processing library strategy: scATAC-seq
Adapter sequences were trimmed from FASTQs using custom python scripts to enable mapping fragments with sequences containing adapters. Paired-end reads were aligned to hg19 or mm10 using BOWTIE2 using the parameter –X2000 allowing fragments of up to 2 kb to align. Duplicates were removed using PICARD tools. Reads were subsequently filtered for alignment quality of >Q30 and were required to be properly paired. Reads mapping to the mitochondria, unmapped contigs and chromosome Y were removed and not considered.
Genome_build: hg19
Supplementary_files_format_and_content: All samples supplied as a count table for all called regulatory elements.
