Blocking Peptide of GFP

Hmm... Does anyone here happen to know what is the epitope of the monoclonal anti-GFP (3E6) antibody?

3E6 is a monoclonal anti-GFP antibody wildly used. We would like to use it for protein purification of the GFP-fusion proteins from mammalian cell lysate. The problem is, we need the blocking peptide to compete and elute the bound GFP-fusion protein from the antibody. Does anyone know the epitope sequence of 3E6?

I spent my whole afternoon googling and found nothing... sigh.

I also sent emails to three companies selling this antibody; hopefully someone will answer me.
