Sample GSM819150 Query DataSets for GSM819150
Status Public on Nov 30, 2011
Title retina, adult, ChAT 50, cone 150, biological rep2
Sample type RNA
 
Source name ChAT-Cre × Rosa26-LSL-RFP : Chrnb4-GFP
Organism Mus musculus
Characteristics cell type: Retinal Starburst amacrine cell and cone photoreceptor mixture
genetic background: mixed FVB/N-Swiss Webster hybrid and C57BL/6J
cell mixture: ChAT 50, cone 150
line: ChAT-Cre × Rosa26-LSL-RFP : Chrnb4-GFP
developmental stage: adult
Growth protocol Mice obtained from Mutant Mouse Regional Resource Centers (MMRRC) were FVB/N-Swiss Webster hybrids that are known to harbor a recessive mutation causing photoreceptor degeneration. These were backcrossed into the C57BL/6J background (RCC) and the F2 generation was used for transcriptome analysis. All other mouse lines had already been in the C57BL/6J background for several previous generations.
Extracted molecule total RNA
Extraction protocol Retinal cells were dissociated using a modified Papain-dissociation protocol of Morrow et al. with a process time of only 15 min. Cells from the retina were sorted. Cell sorting was performed using a MoFlo (Cytomation, Fort Collins, USA) with HQ515/30 (GFP) and HQ616/26 (RFP) bandpass filters. After recording several thousand events the fluorescence gate was set using Summit V 4.3.01 Build 2449 software and a population of events selected. Size and granularity of this population were determined using the forward and side scatter values, respectively, and cell debris discarded by setting a second gate. Finally, after determination of the duration of the events (pulse-width), a third gate was selected that served to exclude cell doublets or clumps. Using these three gates, cells were sorted in single-cell drop mode. A total of 200 cells were sorted at room temperature (RT) into a low-binding tube (Eppendorf) containing 60 µl cell lysis buffer (TRI reagent, Sigma-Aldrich).
Label biotin
Label protocol We used transgenic mouse lines that showed fluorescent-protein expression (RFP or GFP) in distinct cell types within the retina.
 
Hybridization protocol Hybridization was performed with 5 μg biotinylated target, which was incubated with the GeneChip Gene 1.0 ST array (Affymetrix) at 45°C for 16 h. GeneChip Mouse Exon 1.0 ST array was used for the developmental study. Following hybridization, non-specifically bound nucleotides were removed by washing and the specifically bound target was detected using the GeneChip Hybridization, Wash and Stain kit, and the GeneChip Fluidics Station 450 (Affymetrix).
Scan protocol The arrays were scanned using a GeneChip Scanner 3000 7G (Affymetrix) and CEL files acquired using a GeneChip Command Console Software (Affymetrix).
Description RFP/GFP
Data processing Data analysis of gene arrays was done in R (version 2.11.1) using bioconductor as well as in Mathematica (Wolfram Research). For gene arrays, after obtaining the CEL files for each gene array, the files were normalized using the rma function in the oligo package. The resulting text file for gene arrays contained the normalized expression values for 35’556 probes at log2 scale. Mouse gene annotation was downloaded from Affymetrix (MoGene-1_0-st- v1.na30.1.mm9.transcript.txt). Probes were only analyzed when a gene entry was annotated and duplicated annotated genes were removed. All genes are referred to by their NCBI gene symbols.
