Sample GSM184146 Query DataSets for GSM184146
Status Public on Apr 26, 2008
Title zebrafish-35hpf-cd41-sorted-GFP-neg-6_repl-2
Sample type RNA
 
Source name transgenic zebrafish embryos at 35hpf
Organism Danio rerio
Characteristics strain background: AB. Genotype: cd41-GFP transgenic, isolated GFP negative cells
Age: 35 hours post fertilization
Biomaterial provider Gerhard J. Weber
Treatment protocol gata1-GFP+/+(12 somites), lmo2-GFP+/+ (12 somites and 35 hpf)1 and cd41-GFP+/+ (35 hpf)2 cells were separated from GFP-/- cells by flow cytometry at the indicated stages. Sorting was based on propidium iodide exclusion, forward scatter, and GFP fluorescence, using a FACSVantage flow cytometer (Beckton Dickinson). Sorted cell populations were run twice to optimize cell purity. Total RNA from cell-sorted populations was extracted with TRIzol reagent (Invitrogen) and purified on RNeasy resins (Qiagen) according to the manufacturer’s recommendations. Total RNA was subjected to two rounds of linear amplification (Ambion) and hybridized to Affymetrix zebrafish Gene Chips, according to Affymetrix guidelines. After staining with a streptavidin-phycoerythrin conjugate (Molecular Probes), the fluorescence of bound RNA was quantitated by using a Gene Chip scanner (Affymetrix). The raw expression data were calculated and, after pairing of GFP+/+ and GFP-/- samples, statistically analyzed using methods implemented in Bioconductor’s “affy” package and available custom scripts 3,4.

Growth protocol Embryos were obtained by pairwise matings of adult transgenic fish, raised at 28 ºC.
Extracted molecule total RNA
Extraction protocol Trizol extraction of total RNA was performed according to the manufacturer's instructions.
Label biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
 
Hybridization protocol Following fragmentation, 15 microg of cRNA were hybridized for 16 hr at 45C on GeneChip Zebrafish Genome Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
Scan protocol GeneChips were scanned using the Affymetrix GeneChip Scanner.
Description Gene expression data from sorted zebrafish GFP negative cell populations at 35hours post fertilization.
Data processing The data were analyzed with Microarray Suite version 5.0 (MAS 5.0) using Affymetrix default analysis settings and global scaling as normalization method. The trimmed mean target intensity of each array was arbitrarily set to 100.
