Sample GSM3102987 Query DataSets for GSM3102987
Status Public on Jun 30, 2019
Title Wild-type_2
Sample type SRA
Source name WT_testis
Organism Mus musculus
Characteristics strain background: C57BL/6
gender: male
genotype/variation: Wild-type
age: post natal 4 months 2 days
tissue/cell type: Testis
dissociation method: Enzymatic
Extracted molecule total RNA
Extraction protocol Whole testes were dissociated using two different methods, enzymatic and mechanical. Single-cell suspensions were either FACS sorted for enriching different germ cell subpopulations or directly paired to Drop-seq protocol to generate single-cell RNA sequencing libriaries.
Library preparations were perforemd with Drop-seq protocol (Macosko et al. Cell 2015)
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
Data processing Base calls were performed with bcl2fastq.
Sequenced reads were tagged with molecular(UMI) and cell barcodes. Then reads with low quality scores were removed and the adaptor sequences were trimmed. 
Reads were aligned to Mus_musculus.GRCm38.76 genome with STAR (v. 2.5.3a) with default configuration.
STAR aligned reads were merged with tagged SAM file to recover cell/molecular barcode information. Then the reads were annotated with exon and other annotation tags.
Digital gene expression matrix was extracted by counting the number of unique UMIs per gene within individual cell from exon-tagged bam files.
Additional step of bead synthesis error correction was performe by collapsing UMI counts when the first 11 bases of cell barcodes were the identical.
Genome_build: mm10
Supplementary_files_format_and_content: Digital Gene Expression(DGE) matrix of gene counts for each cell. Columns are cells and rows are genes.
