Sample GSM3721773 Query DataSets for GSM3721773
Status Public on Feb 12, 2020
Title MS patient 1-2
Sample type SRA
 
Source name CNS Percoll pellet
Organism Homo sapiens
Characteristics subject status: Multiple sclerosis (MS) patient
subject group: secondary progressive MS (SPMS)
Treatment protocol Following rapid autopsy, samples were immediately incubated in Hibernate (Life Technologies, #A1247601) for 8-18 hours prior to processing.
Growth protocol N/A
Extracted molecule total RNA
Extraction protocol A cell suspension was generated by papain digestion, neutralization, and 70um filtration of cell extract. Cells were centrifuged, resuspended in 30% Percoll, centrifuged, washed in PBS, and cell density was quantified. Cells were suspended in PBS and 16% Opti-prep.
Libraries were created according to the Drop-seq protocol in Macosko et al. Cell 2015. Following reverse transcription, exonuclease I treatment, and PCR, cDNA libraries were quantified and 600 pg of cDNA was tagmented using Nextera XT library prep kit.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 4000
 
Description Sample 5
2_HMVNKBBXX.2.CGTACTAG
Data processing Reads were processed using the DropSeq analysis pipeline developed by the McCarroll lab (http://mccarrolllab.com/dropseq/)
Individual cells were tagged with barcodes, and transcripts within each cell were tagged with distinct UMIs (Unique Molecular Identifiers).
Reads were trimmed at 3' end to remove poly(A) tails with length greater than 5 and trimmed at the 5' end for adapters
Reads with barcode base quality less than 10 were filtered out
Raw reads were aligned to human (GRCh38) genome by STAR (v2.4.0) with default settings
UMI counts expression matrix were generated using Dropseq Tools software (v1.13.1)
Genome_build: GRCh38
Supplementary_files_format_and_content: Tab-delimited text file consisting of UMI gene counts for cells with minimum 200 genes.
