Sample GSM1826870 Query DataSets for GSM1826870
Status Public on Dec 29, 2015
Title Mushroom body neuroblast replicate 2
Sample type SRA
 
Source name Mushroom body
Organism Drosophila melanogaster
Characteristics cell type: neuroblast
age: 50hr after larva hatch
num_cells (number of cells in the sample): 101
ercc_mix (1 or 2): 1
ercc_5 (10^-5 dilution of ercc in ul): 1
Growth protocol Newly hatched Fly larvae were first synchronized with maxiumum 2 hour age difference and then grew at 25C until dissection
Extracted molecule total RNA
Extraction protocol 30 fly larvae brain tissues were dissected at defined ages, digested with a mixture of pronase(1mg/ml) and dispase (1mg/ml) for 30 min at 25C, washed, triturated and 10 GFP labeled cells were sorted with a robotic sorter and stored at -80C in XB buffer from PicoPure kit (life technologies, KIT0204). Total RNA from around 100 pooled cells was extracted using PicoPure kit.
Extracted RNA was amplified using Ovation RNA-Seq System V2 (NuGEN, #7102). 1~1.5 ug of the amplified material was used for library construction using Encore NGS Multiplex System (NuGEN, #0314).
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
 
Data processing Illumina Casava and BCL2FASTQ1.8.3 were used for basecalling
Sequenced reads were trimmed for NuGEN and Illumina adaptor sequences using cutadapt v1.7.1 with parameters --overlap=7 --minimum-length=30. Ribosomal RNA, mitochondrial and phiX sequences were filtered using bowtie2 v2.1.0 with default parameters. Remaining reads were then mapped to mm10 genome using STAR v2.4.0i with parameters --chimSegmentMin 15 --outFilterMismatchNmax 3.
Uniquely mapped reads were assigned to genes using HTSeq v0.6.1p1 with parameter -s no -m intersection-nonempty and using iIllumina UCSC/dm3 annotation. FPKM for a gene was calculated by dividing assigned count by the sum of lengths of all exons belonging to the gene and then by total number of reads in million.
