One possible problem... if you used undenatured cell proteins for
antigen... the proteins on blots will be denatured... However, it might
still be useful for your purposes. Sounds like your going to get
numerous positive clones and numerouse false positive clones with such
heterogeneous antigen and antibodies. Be prepared for a very tiresome
and laborious screening ordeal.
