[Yeast] GAL4-DBD antibodies for immunofluorescence

Hello, All! 

I am looking for antibodies against the GAL4-DBD to verify that my bait constructs are indeed nuclear-localized. My bait is in pGBKT7 (Clontech Matchmaker). None of the commercially available antibodies (Clontech, Abcam, Santa Cruz) for GAL4-DBD are verified for immunofluorescence. I was wondering if anyone has used a GAL4-DBD antibody for IF and how well it worked. I have several bait constructs so I am hoping that I can use one antibody to verify nuclear localization for all of them. I only have an antibody against one of my baits and it works weakly for IF. 

Also, I would also welcome any comments, hints, suggestions, or advice on general yeast two-hybrid techniques (especially library transformation) prior to running my actual Y2H screen. 

Many thanks in advance! 

P.S. I can be e-mailed at jennifer.chang from nyumc.org or at jennifer.chang02 from gmail.com
