| Title |
Ovarian Cancer Human Serum 4 |
| Sample type |
RNA |
| |
|
| Source name |
human serum
|
| Organism |
Homo sapiens |
| Characteristics |
sample type: serum
disease state: ovarian cancer
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA from serum was isolated using the mirVana PARIS RNA Isolation Kit (Ambion). In all instances RNA isolation was performed according to the manufacturer’s instructions using 300 ml serum.
|
| Label |
Cy3
|
| Label protocol |
miRNA labeling was performed as described in Agilent miRNA microarray protocol version 2.0 using Agilent miRNA labeling kit. 100 ng of total RNA was dephosphorylated with calf intestine alkaline phosphatase for 30 min at 37°C. Denaturation was performed by adding DMSO and incubating at 100°C for 6 min and immediately transferred to ice water bath. Ligation was performed with pCp-Cy3 at 16 °C for 2 h. The labeled samples were dried completely in a vaccum concentrator and resuspended in 18 ul of nuclease free water.

|
| Hybridization protocol |
The hybridization mixture [10X GE blocking agent (4.5 ul), 2X Hi-RPM hybridization buffer (22.5ul)] along with labeled miRNA sample was heated for 5 min at 100 °C and immediately cooled to 0 °C. Each 45 mL sample was hybridized onto a microarray at 55 °C for 21 h. Slides were washed 5 min in GE wash buffer 1 at RT and again for 5 min in GE wash buffer 2 at 37 °C, followed by an acetonitrile wash for 10 sec at RT to dry the slides completely.
|
| Scan protocol |
Slides were scanned immediately after washing on the Agilent DNA Microarray Scanner (G2505B ) using one color scan setting for 8x15k array slides (Scan Area 61x21.6 mm, Scan resolution 5um, Dye channel is set to Green and Green PMT is set to 100%, No XDR).
|
| Description |
miRNA expression
|
| Data processing |
The scanned images were analyzed with Feature Extraction Software 10.7.3.1 (Agilent) using default parameters (protocol miRNA_107_Sep09 and Grid:029297_D_F_20101116) to obtain background subtracted and spatially detrended Processed Processed Signal intensities. Features flagged in Feature Extraction as Feature Non-uniform outliers were excluded.
