Default Methylation patterns through Methyl-Seq

Dear group:
Hello! I am interested in learning the possibilities about identifying DNA methylation patterns at CpG islands. Since many CpG repeats located in repetitive areas of genome, I would like to know how a targetted methy-seq is done using either MeDIP-Seq or Methyl-Seq (as described by Brunner AL et al. in GR june-2009).
What would be the options for selecting only those important CpGs and not sequencing entire genome.
I appreciate your help and input. thanks Adrian.

We used a combination of bisulfite sequencing and hybrid capture ("Bisulfite Capture"), which allows you to select regions where you are interested in the methylation status. Check out this paper, which may be a useful method for what you want to do:

If I would attach so called MID tags together with the methylated illumina adaptors. Do you think it would be possible to capture fragments from several samples with the same array and be able to seperate them after sequencing?

hi. i am wondering if we are able to deep-sequence the methylation pattern of the whole genome? i mean can we get the whole genome methylation state aside from the sequence information?
thanks a lot.

Yes! See:
