A total of 4 μg of the immunoprecipitated and input fraction DNAs were analyzed using the Human DNA Methylation 2.1 M Deluxe Promoter Arrays (Roche NimbleGen, Madison, WI, USA) by the NimbleGen Service Group, who performed the quality control, labeling, hybridization, and scanning.
This template DNA fragment was prepared by PCR using the human genomic DNA as a template.
Using the human female genomic DNA (positive control) we found that the median intra- and inter-assay coefficient of variation (CV) for 115bp were 4% (IQR, 3%-63%-6nd 4% (IQR, 3%-43%-4%spectively.
To test whether the cnidarian and sponge variants of these proteins possess the structural determinants necessary for them to interact and bind DNA together in a manner homologous to the human complex, we modeled their three dimensional structure using the human AML1 RUNX1 RD-CBFβ-DNA complex AML1 RUNX1 RD-CBFβ-DNA (see Methods).
Using the protocol optimized as above, we prepared indexed TMS libraries from 3,000 to 10 ng of human and mouse DNA using the human and mouse RNA probe sets obtained from Agilent, respectively (Table 1).
THP-1 cells were transfected with AGER1, SIRT1 or short-hairpin RNA AGER1 (0.5 µg of DNA) by using the human monocyte cell line nucleofector kit (Amaxa Biosystems, Cologne, Germany).
The promoter DNA methylation data was generated using the Infinium Human DNA Methylation27 BeadArray platform (Illumina, San Diego, California).
By performing a BLAT search using the entire human DNA sequence of the gene, we recovered the proper exon sequences for both the chimpanzee and the orangutan.
We report the genome-wide analysis of methylation differences in two families with monozygotic twins discordant for schizophrenia using the NimbleGen Human DNA Methylation Promoter Plus CpG Island 720k Array.
PCR protocol was as follows: initial denaturation step of 94°C for 3 min was followed by 35 cycles of 94°C for 1 min, 57°C for 1 min and 72°C for 1.30 min and final extension step at 72°C for 7 min. Authenticity of the PCR products was confirmed by direct sequencing and Southern hybridization, using the corresponding human DNA as probe.
More details can be found in Additional file 2. As a running example to illustrate the new features, we used the human protein-DNA data now available with DREM 2.0 to analyze an expression experiment studying the effects of asbestos on human lung adenocarcinoma cells (A549) [ 39].
