| Title |
col-0_no_antibody_2 |
| Sample type |
genomic |
| |
|
| Source name |
Immature floral tissue, unopened buds
|
| Organism |
Arabidopsis thaliana |
| Characteristics |
Columbia-0
|
| Treatment protocol |
no treatment
|
| Growth protocol |
All plants were grown in potting soil (Metro Mix 250; Grace-Sierra, Boca Raton, FL) at 23˚C under a 16-hour light/8-hour dark cycle.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Genomic DNA was isolated from the immature floral tissue following instructions from the manufacturer (Qiagen, DNeasy Plant mini kit). 2 µg of fragmented genomic DNA was incubated under the same conditions as the methylcytosine immunoprecipitation samples, except no antibody was added.
|
| Label |
biotin
|
| Label protocol |
Genomic DNA from the "no antibody" control was amplified using the Sigma GenomePlex WGA1 kit as per manufacturer's instructions to yield 15 µg, fragmented by incubation with DNaseI (0.05 U/µg DNA) for 10 min at room temperature, then denatured. DNA was labeled by incubating the fragmented DNA with biotin-16-dUTP, biotin-16-ddUTP and terminal transferase for 90 min at 37˚C.

|
| Hybridization protocol |
The Arabidopsis Tiling 1.0R whole genome tiling array was hybridized for 16 h, washed and stained with a streptavidin-phycoerythrin conjugate on the Affymetrix Fluidics Station 450 accordingto the standard Affymetrix protocol.
|
| Scan protocol |
GeneChips were scanned on Affymetrix Scanner G7
|
| Description |
Col-0 control (no antibody) replicate 2
|
| Data processing |
Gene chip data files were processed using TileMap. This array was one of two control samples that were used to identify methylated regions in the methylcytosine immunoprecipitation reactions.
