repeating chipseq or chipseq with another antibody

[hawainpanda]

I was wondering which was the preferred method?
Would people prefer performing chipseq with two diff antibodies, or repeating chipseq with same antibody?

Not sure what you mean. Once an antibody is validated as specific, it should be fine to use. The more biological and technical replicates you perform the better.

As a reviewer, ChIP-Seq with a different antibody would definitely add strength to a manuscript. Biological triplicates with both antibodies would be ideal. I think people sometimes put too much faith in antibody specificity, so I think data generated with two different antibodies is much more convincing. Also, an IP-Western with an IP done with one antibody and the Western done with another is always a strong piece of data to add to a manuscript, in my opinion.
