| Title |
CD45+/Sca1+_Muscle_+Ctx/BMT_rep2 |
| Sample type |
RNA |
| |
|
| Source name |
CD45+/Sca1+ cells isolated from the muscle
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6, Age: 6-8 weeks old, Tissue: muscle
|
| Treatment protocol |
Injury with Cardiotoxin (Ctx) and BM transplantation (BMT)
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted using RNeasy Micro Kit (Qiagen, Valencia, CA) following the protocol supplied by the manufacturer. Disposable RNA chips (Agilent RNA 6000 Nano LabChip kit, Agilent Technologies, Waldbrunn, Germany) were used to determine the concentration and purity/integrity of RNA samples using Agilent 2100 Bioanalyzer.
|
| Label |
biotin
|
| Label protocol |
One-cycle target labeling assays were performed, using Affymetrix standard protocols (Affymetrix, Santa Clara,CA). Briefly, biotin-labeled target synthesis was performed, starting from 1 µg of total cellular RNA, according to the protocol supplied by the manufacturer (Affymetrix, Santa Clara, CA). Labeled cRNA was purified using Affymetrix GeneChip Sample Cleanup Module and fragmented (20 µg) as described in the Affymetrix GeneChip protocol. Disposable RNA chips (Agilent RNA 6000 Nano LabChip kit, Agilent Technologies, Waldbrunn, Germany) and Agilent 2100 Bioanalyzer were used to determine the cRNA concentration/quality as well as to optimize the cRNA fragmentation.

|
| Hybridization protocol |
The fragmented cRNA was then hybridized to an identical lot of Affymetrix Mouse430A GeneChip arrays for 16 hours. GeneChips were washed and stained using the instrument’s standard Eukaryotic GE WS2v4 protocol, using antibody-mediated signal amplification.
|
| Scan protocol |
GeneChip were finally scanned using the Affymetrix GeneChip scanner 3000, enabled for High-Resolution Scanning.
|
| Description |
Synthesis of biotinylated cRNA targets, arrays hybridization (Mouse430A GeneChip, Affymetrix, Santa Clara,CA), staining and scanning were performed using Affymetrix standard protocols starting from 1μg of total RNA.
|
| Data processing |
Scaling to TGT value=250. The GeneChip-Operating-Software (GCOS) absolute analysis algorithm was used to determine the mRNA expression levels (Signal), while the GCOS comparison analysis algorithm was used in order to compare gene expression levels between two samples.
