Sample GSM6658959 Query DataSets for GSM6658959
Status Public on Jul 09, 2023
Title CD8_Spleen_CSF1R
Sample type SRA
Source name Spleen
Organism Mus musculus
Characteristics tissue: Spleen
cell line: CD8 T cells
cell type: CD8 T cells
genotype: WT
treatment: anti-CSF1R antibody
Treatment protocol Tumor-bearing mice were treated the equivalent dose (30 mg/kg) of all components with 3 days interval for total 3 doses, followed by CD8 T cell isolation for TCR sequencing.
Growth protocol Primary CD8 T cells were isolated by MACS CD8 T cell microbeads from tumor, spleen, and LN.
Extracted molecule total RNA
Extraction protocol Trizol protocol for tissue RNA extraction. Extracted RNA were quantificated by using Qubit fluorometer with Qubit RNA BR Assay Kit
Libraries were prepared using QIAseq Immune Repertoire RNA Library Kit (GeneGlobe configuration no. IMMM-001Z-12) following the directions of the manufacturer.
QIASeqTargeted enrichment & sequencing
Library strategy OTHER
Library source transcriptomic
Library selection other
Instrument model Illumina MiSeq
Data processing All data processing steps are using QIAseq TCR Panel Immune Repertoire RNA Library Kit (version 2.01).
Trim reads: First trim from the reads the constant regions generated by the enrichment protocol, and move the UMI sequence to the read indentifier line.
Down-sample reads: Randomly discard the reads until the remaining reads contain about 8 reads per UMI.
Build consensus reas: Error corrected consensus reads are generated by grouping multiple reads that putatively came from the same input simple molecule, based on three factors: (1) the UMI tag sequence; (2) the endogenous sequence near the random fragmentation and UMI ligation site; and (3) the full read sequence.
Merge overlapping R1 and R2 reads: R1 being entirely VDJ sequence, and R2 being V-only.
Split reads by genes (TRAC, TRBC, TRDC, TRGC).
Align the reads to the V-region models and trim overhang regions.
Run IMSEQ to generate clonotype calls and quantities. (parameters: -ev 0.15 -ma -sfb)
Compute diversity metrics. (Total clonotype count, Clonotypes within the top 50% of UMIs, Shannon-Wiener diversity index, Inverse Simpson diversity index)
Assembly: mm10
Supplementary files format and content: QIAseqRNA-immune-repertoire-TCR.clonotypes file in .txt format for three sample groups.
