Sample GSM682275 Query DataSets for GSM682275
Status Public on Sep 01, 2012
Title larval per0 NCB-LNvs at CT-15, biological rep1
Sample type RNA
 
Source name Drosophila larval per0 NCB-LNvs at CT-15
Organism Drosophila melanogaster
Characteristics tissue: FACs-purified LNvs
genotype: per0, yw; Pdf-Gal4/UAS-NCB; Pdf-RFP
developmental stage: L3 larval stage
Treatment protocol Dissected brains (L3 larvae) were transferred to Schneider’s Insect Medium (Sigma) in non-stick tubes (Neptune) and were kept on ice throughout. Prior to dissociation, brains were washed with ice-cold PBS buffer. For dissociation, we followed the method of Wegener et al: brains transferred to a 50:50 mix of 1X Collagenase (Sigma): 1X Dispase II (Roche) and incubated for 2hr at 25°C. After 2hr, the dissociation solution was replaced with Schneider’s medium with 10% FBS (Fetal Bovine Serum), brains were triturated 100x with a pipette, and strained through a 35mm nylon mesh filter. Cells in Schneider’s medium / 10% FBS were kept on ice for transport FACS.
Growth protocol All larval genotypes raised at 25C in 12:12hr Light/Dark cycle.
Extracted molecule total RNA
Extraction protocol The 0.01%-most RFP+ cells (150 - 300 cells) were isolated by FACS, and sorted directly into Arcturus PicoPure RNA extraction buffer. mRNA was amplified using the NuGen WT-Ovation™ Pico System to yield ~ 5ug biotin labeled, fragmented, single-stranded cDNA
Label biotin
Label protocol Affymetrix protocol
 
Hybridization protocol Following fragmentation, 5 ug of cDNA were hybridized for 20 hr at 45C on GeneChip Drosophila Genome Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
Scan protocol GeneChips were scanned using the Hewlett-Packard GeneArray Scanner G2500A.
Description Gene expression data from per0 NCB-expressing LNvs at CT-15
Data processing Raw hybridization intensities from each CEL Affymetrix file (Drosophila 2.0 GeneChip) were analyzed using gcrma algorithm in Matlab. Intensities were quantile-normalized across all replicates and experiments to yield a single expression measure for each probeset on the chip.
