Sample GSM4193068 Query DataSets for GSM4193068
Status Public on Nov 27, 2019
Title RNAExp31
Sample type SRA
Source name Jurkat cell line and Nalm6 cell line
Organism Homo sapiens
Characteristics cell line: Jurkat cell line and Nalm6 cell line
molecule type: various targeted RNA transcripts
Growth protocol Jurkat cells and Nalm-6 cells were obtained from America Type Tissue Collection (ATCC). Cells at a density of ~1×106/mL were fixed in RPMI medium without serum in 1.6% paraformaldehyde (Electronic Microscopy Sciences) for 10 min at room temperature under gentle agitation. Cells were pelleted and permeabilized with ice-cold methanol for at least 10 min on ice. Once in methanol cells can be stored at −80 °C for several weeks without loss of antibody signal or RNA degradation.
Extracted molecule total RNA
Extraction protocol QIAquick Gel Extraction Kit (Qiagen, 28704).
PCR with Illumina dual index primers
Library strategy OTHER
Library source transcriptomic
Library selection other
Instrument model Illumina NextSeq 500
Data processing Library strategy: Single cell barcoding by split-pool synthesis via ligation
FLASH-1.2.11 was used to merge the paired end reads.
seqtk-v1.2 was used to convert merged fastq file to fasta format.
The reads were then parsed to identify cell-id and marker-id based on the white-list info in the associated qdata folder, deduplicated based on cell-id and marker-ids and finally chimeric reads were filtered out.
Expression counts were then used to remove putative debris and doublets cells based on the criteria listed in Singlet_settings.txt in the corresponding qdata folder.
Expression counts matrix was then normalized by scaling the counts by row-means and multiplying by a factor of 10.
A github repository for the software used to process the raw-fastqs is available at the following location:
Supplementary_files_format_and_content: Tab separated text files containing jittered expression counts (both normalized and un-normalized) for different markers for each individual cell
The *tar.gz contains various files containing white-list information for cell-barcode ids, anchor-sequence info, marker-sequence info and settings information for removal of cell-debris and cell-doublets. The files in this folder is used to process the raw fastqs for each of the experiment.
