Background

The cAMP response element binding protein (CREB), also known as CREB1, belongs to the bZIP superfamily of transcription factors, containing a basic domain that mediates DNA binding and a leucine zipper domain that facilitates dimerization. Within the promoter of target genes, CREB dimers bind cAMP response elements, defined by the palindromic consensus sequence TGACGTCA.

FAQs for CREB Antibody (AF2989). (Showing 1 - 1 of 1 FAQs).

1. May I know which creb1 antibody is good for ChIP? I found a paper using your rabbit polyclonal creb1 antibody for ChIP but they didn't indicate the catalog number.
   • We are not aware of any of our Creb1 antibodies being used in ChIP at this time. If you can provide us with the PMID of the paper you are referring to I can contact the author. Otherwise, you can use our Innovators Reward Program to try an antibody in a novel species and application.
