DNA methylation · human · 8 samples

What it is: DNA methylationChemical marks on DNA that help switch genes on or off.
Organism: Homo sapiens (human)
Samples: 8 samples
Data you can get: A processed expression table (series matrix) and the array files, from NCBI.

Summary (written by the submitters)

Two samples with known methylation differences. Sample A is NA 10923 from Coriell Institute for Medical Research. It is a B-Lymphocyte sample from a male donor. Sample B is HTB-38 cell line from ATCC (http://www.atcc.org). It is a colon cancer sample from a female donor. Sample A and B were normalized into the same concentration, and then mixed in five different titration ratios: 100:0, 90:10, 75:25, 50:50 and 0:100

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

3 · The original raw files

Whole study · RAW.tar

Everything the authors deposited as one archive (GSE23789_RAW.tar), including the raw array or instrument files. Can be large; the picker in step 2 takes just the samples you need.
