Sample GSM7596836 Query DataSets for GSM7596836
Status Public on Oct 01, 2023
Title Ferret1_All_S1
Sample type SRA
 
Source name Retina
Organism Mustela putorius furo
Characteristics tissue: Retina
cell type: Retinal neurons
Treatment protocol None
Extracted molecule nuclear RNA
Extraction protocol Retinas were dissected in Ames solution (Sigma-Aldrich; equilibrated with 95% O2/5% CO2 for all use) immediately following enucleation. They were dissociated in papain, followed by FACS sorting. Cells were stained for either THY1/CD90 to enrich for RGCs or for CD73 to deplete photoreceptors.
Single cell libraries were generated using the Chromium 3’ V3 platform (10X Genomics, Pleasanton, CA) according to the manufacturer’s protocol. Briefly, single cells were partitioned into Gel-beads-in-EMulsion (GEMs) where nuclear lysis and barcoded reverse transcription of RNA would take place to yield full-length cDNA; this was followed by amplification, enzymatic fragmentation, and 5’ adaptor and sample index attachment to yield the final libraries.
Single cell RNA sequecning (10X Genomics)
 
Library strategy RNA-Seq
Library source transcriptomic single cell
Library selection cDNA
Instrument model Illumina NovaSeq 6000
 
Data processing We used cellranger (v7.0, 10X Genomics) to align the sc- and snRNA-seq datasets, following manufacturer’s instructions. For each species, sequencing reads were demultiplexed into distinct samples and the .fastq.gz files corresponding to each sample were aligned to reference transcriptomes to obtain binary alignment map (.bam) files.
Assembly: MusPutFur1.0
Supplementary files format and content: To include both exonic and intronic reads in the quantification of gene expression for each sample, regardless of cellular or nuclear origin, we applied velocyto to the corresponding .bam files. This generated two separate gene expression matrices (GEMs; genes x cells) for each sample, corresponding to “spliced” and “unspliced” reads. The two GEMs were summed element by element to obtain “total” GEM for each sample.
Supplementary files format and content: GEMs from different sample runs were combined (column-wise concatenated) to yield a full species’ GEM.
