| Title |
normal (grade 1) articular cartilage, superficial zone, rep 2 |
| Sample type |
RNA |
| |
|
| Source name |
bov4, cartilage, superficial zone
|
| Organism |
Bos taurus |
| Characteristics |
bovine id: bov4
age: mature (14-30 months)
tissue: cartilage, superficial zone
|
| Treatment protocol |
Osteochondral cores were obtained from weight bearing area of the distal femoral condyles of bovine knees. The bone portion of each osteochondral core was embedded in paraffin in a standard plastic cassette to allow fixation of the plug in the microtome. The entire cartilage was sliced into 50 μm thick sections from the cartilage surface downwards to the calcified cartilage using a microtome (Microm HM 325, Thermo Scientific, Walldorf, Germany). Each section was transferred to one well of a 96-well plate filled with RNAlater (Qiagen). The sections were segregated into zones for RNA isolation as follows: The upper 10% of zonal slices were allocated to the SZ, the middle 40% were allocated to the MZ and the lower 30% were allocated to the DZ. To avoid overlap between zones, regions of approximately 200 μm between the SZ and MZ and between the MZ and DZ were discarded.

| Growth protocol |
skeletally mature animals (14-30 months of age)
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated from cartilage zones using the Qiagen Rneasy kit with Dnase digestion following the manufacturer's instructions. Total RNA was quantified using NanoDrop (ND-1000). Sample quality was checked with the Agilent 2100 Bioanalyzer using the RNA 6000 Pico LabChip (Agilent Cat. # 5065-4473).
|
| Label |
biotin
|
| Label protocol |
Five nanograms (5 ng) of total RNA was taken through the NuGEN Ovation Pico WTA System version 1.0. Post amplification, 5ug of the purified cDNA product was fragmented and labeled using NuGEN Encore Biotin Module.
|
| |
|
| Hybridization protocol |
The post fragmentation and labeling product (5ug) was used for the hybridization cocktail and hybridized overnight to the Affymetrix GeneChip Bovine Genome Array (Affymetrix P/N 900562) following the NuGEN Encore Biotin Module protocol. Hybridization and scanning of samples to arrays was performed using the standard NuGEN Hybridization, Cocktail Assembly, and Fluidics Protocols using Affymetrix’s GeneChip Hybridization, Wash, and Stain Kit (Affymetrix P/N 900720), according to Appendix V1 of the NuGEN Encore Biotin Module protocol.
|
| Scan protocol |
Chips were scanned using the Affymetrix GeneChip Scanner 3000 7G with default settings and a target intensity of 250 for scaling.

| Description |
062211_Bov4SZ
normal mature (14-30 months) bovine articular cartilage from medial and lateral condyles of knee joints
|
| Data processing |
Data was normalized using both RMA and dCHIP.
Log2 RMA signals are presented in the data table below.
Log2 dCHIP signals can be found in a supplementary file linked to the Series record.
The normalized data have filtered out the Affymetrix Control probes and the 30% lowest variant probesets.
