Title |
larval LNvs at CT-15, biological rep2 |
Sample type |
RNA |
|
|
Source name |
Drosophila larval LNvs at CT-15
|
Organism |
Drosophila melanogaster |
Characteristics |
tissue: FACs-purified LNvs genotype: yw, 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 wildtype 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.
