Project description:Histone 3 lysine 4 and histone 3 lysine 9 methylation in wild type and ddm1 Arabidopsis thaliana seedlings. The purpose of the chromatin immunoprecipitation/microarray (ChIP/chip) experiment is to determine which regions of a genome are enriched for a particular histone modification in a single Arabidopsis thanliana genotype. Chromatin immunoprecipitation with antibodies raised against dimethyl histone-H3 lysine-9 (H3mK9) or dimethyl histone-H3 lysine-4 (H3mK4) is performed on a selected genotype. This purified DNA from each immunoprecipiation (mH3K9, mH3K4, no antibody control) is used for random amplification to increase the quantity of DNA for microarray hybridization. The amplified DNA from each experimental sample is then labeled with Cy5 and hybridized against total input DNA from the corresponding genotype, labeled in Cy3. In a single hybridization, the total input DNA serves as a baseline and is compared to the immunoprecipitated samples. Ratios of normalized signal intensities were calculated to identify enrichment of a particular sequence after immunoprecipitation, in comparison to the total input DNA. Dye swap analysis is carried out to take account of experimental variation by repeating the hybridization with identical samples labeled with Cy3 and Cy5, respectively. This SuperSeries is composed of the following subset Series: GSE1333: EV49+50, Histone 3 Lysine 4 methylation in wild-type Arabidopsis thaliana seedlings GSE1334: Histone 3 Lysine 4 methylation in ddm1 Arabidopsis thaliana seedlings GSE1335: EV104+105, Histone 3 Lysine 4 methylation in ddm1 Arabidopsis thaliana seedlings GSE1336: Ev106+107, Histone 3 Lysine 4 methylation in WT Arabidopsis thaliana seedlings GSE1337: EV51+52, Histone 3 Lysine 9 methylation in wild-type Arabidopsis thaliana seedlings GSE1338: EV59+60, Histone 3 Lysine 9 methylation in ddm1 Arabidopsis thaliana seedlings GSE1339: Histone 3 Lysine 9 methylation in wild-type Arabidopsis thaliana seedlings GSE1340: EV110+111, Histone 3 Lysine 9 methylation in ddm1 Arabidopsis thaliana seedlings Refer to individual Series
