Sample GSM419121 Query DataSets for GSM419121
Status Public on Feb 01, 2010
Title CoCl2 3h 2
Sample type RNA
 
Channel 1
Source name HaCaT cells pool
Organism Homo sapiens
Characteristics cell type: keratinocytes (HaCaT)
reference: common reference
Treatment protocol Cells were exposed to 30 µg/ml WC (153 µM), 33 µg/ml WC-Co (153/51 µM), or 3 µg/ml (51 µM) cobalt chloride by mixing RPMI 5 % FBS with 10 fold concentrated stock solutions. Exposure was performed in the dark with 5 independent replicates (performed at different days using different cell passage numbers). Controls were performed by with the water used for the preparation of particle suspensions.
Growth protocol HaCaT cells were maintained in RPMI medium (‘Roswell Park Memorial Institute’ medium; Biochrom, Karlsruhe, Germany) supplemented with 5 % (v/v) FBS and 1% (v/v) penicillin/streptomycin. Cells were cultured in monolayers at 37°C in a humidified, 5 % (v/v) CO2-atmosphere and sub-cultured twice a week in 75 cm² flasks. Cells were seeded at densities of 200.000 cells/ml for 3d of exposure or 500.000 cells/ml for 3h of exposure, respectively in a final volume of 10 ml per 75 cm² flasks.
Extracted molecule total RNA
Extraction protocol Total RNA extracted using Trizol following manufacturer's instructions.
Label Cy5
Label protocol Synthesis of cDNA, cRNA and cRNA-labeling was performed with the Agilent Low RNA Input Linear Amplification Kit according to the manufacturer’s instructions. cRNA was labelled with Cy3 (controls and treatments) and Cy5 (common reference).
 
Channel 2
Source name HaCaT cells
Organism Homo sapiens
Characteristics cell type: keratinocytes (HaCaT)
exposure time: 3 hours
treatment: CoCl2 51 µM (= 3µg/ml cobalt)

Hybridization protocol Hybridization was performed using the Agilent Gene Expression Hybridization Kit following manufacturer's instructions.
Scan protocol Scanned on an Agilent scanner. Images were quantified using Agilent Feature Extraction Software (version 9.5.3.1 or 10.1.1.1).
Description Biological replicate 2 of 5, harvested after several passages.
Data processing Feature extraction files (processed signals) were used for statistics.
