| Title |
Flk2_pos_MPP_3 methyl-depleted |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
Methyl-depleted fraction from Flk2_pos_MPP_3
|
| Organism |
Mus musculus |
| Characteristics |
cell type: Flow sorted MPPFL+ cells from mouse bone marrow (Lin- Il7ra- c-Kit+ Sca-1+ CD34+ Flk2+)
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Genomic DNA (gDNA) were isolated using DNeasy kit (Qiagen) according to the manufacturer’s protocol. For each sample, 1~5 µg of genomic DNA was sheared into 1.6-3kb DNA size fragments, digested with McrBC, and fractionated on a 1% agarose gel alongside the sheared input (UT) fraction to enrich for the methyl-depleted (MD) fraction. The UT and MD fractions were purified and whole genome amplified using the WGA2 kit (Sigma) according to the manufacturer's protocol.
|
| Label |
cy5
|
| Label protocol |
2 µg of DNA was directly labeled by Klenow (New England Biolabs) random priming with Cy3 nonamers for the input (UT) fraction and Cy5 nonamers for the methyl-depleted (MD) fraction per manufacturer's protocol (methylation_userguide_v5p0.pdf).

|
| |
| Hybridization protocol |
The labeled DNA was precipitated with 0.1 volume 5M NaCl and 1 volume isopropanol, and hybridized in NimbleGen Hybridization solution master mix. Arrays were hybridized in Maui hybridization stations for 16-20 h at 42C, and washes were completed using manufacturer's protocols (methylation_userguide_v5p0.pdf).
|
| Scan protocol |
Arrays were scanned on a GenePix 4000B scanner per manufacturer's protocol (http://www.nimblegen.com/products/lit/methylation_userguide_v5p0.pdf).
|
| Data processing |
Arrays were processed using Nimblegen's standard protocol for Nimblescan 2.4 software (http://www.nimblegen.com/products/lit/methylation_userguide_v5p0.pdf).
