| Title |
WC-Co 3d 5 |
| 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).
