Sample GSM2518782 Query DataSets for GSM2518782
Status Public on May 03, 2017
Title mel_rep6
Sample type SRA
 
Source name Drop-seq of whole embryo
Organism Drosophila melanogaster
Characteristics developmental stage: mixture stage 10 to 17 batch1
fixation: 80% methanol/PBS
cell type: dissociated cells
Growth protocol Egg lays occurred in 2 hour intervals after 3x 1 hour pre-lays; embryos were aged for 6 hours (D. melanogaster) at room temperature.
Extracted molecule polyA RNA
Extraction protocol Methanol-fixation was adapted from Stöckius et al. 2009 (Nat. Methods). To avoid cell clumping, 8 volumes (800 µl) of methanol p. a. (pre-chilled to -20˚C) were added drop-wise, while gently mixing or vortexing the cell suspension. Macosko et al. 2015 Cell; Online-Dropseq-Protocol-v.3.1.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
 
Description single-cell transcriptomics
Data processing Cell and molecular barcodes were extracted from read1 and added as tags using Drop-seq tools v1.12. Sequenced reads were trimmed for polyA stretches, SMART adaptor sequences and low quality filtering using Drop-seq tools v1.12. Trimmed sequenced reads were mapped to hg38 and mm10 using STAR_2.4.0j. Mapped reads were sorted using samtools v1.2 and merged with cell and molecular barcodes using Drop-seq tools v1.12. Gene annotation tags were added and bead synthesis errors were detected and corrected using Drop-seq tools v1.12. Cumulative fraction of reads per cell was computed using Drop-seq tools v1.12, inflection point was computed using dropbead v.0.2. The digital gene expression matrices were computed using Drop-seq tools v1.12.
Genome_build: hg38, mm10
