Hybridization protocols as described in Ambion Probeset (Cat#1561v1) and Ambion miRNA Labeling Kit (Cat#1562)
|
| Scan protocol |
Processed slides were scanned using the microarray scanner GenePix 4000B (Axon), with the lasers power set at maximum with fixed PMT value and a scan resolution of 10 um.
|
| Description |
miRNA expression profiling was performed on ex vivo differentiating erythroid cultures derived from human UCB-CD34 cells. Day 0 samples were freshly isolated CD34 cells. This is used as the baseline for comparison with ex vivo induced erythroid differentiation cultures from Day 2, 4, 6, 9 and 12.
|
| Data processing |
Data in VALUE column are median signal intensity after background subtraction, and normalized by dividing with the average signal (after background subtraction) of the sample
