The best product of fixation offered by Dr. Bogen evaluated one epitopes of diagnostic antigens, i.e., antibodies. A bit additional complicated styles offered by Dr. O’Leary evaluated the effects of fixation on straightforward proteins, RNA, and DNA, and the most complex design presented by Dr. Otali permits evaluation of the effects of fixation on intact mobile preparations. The complexity of the challenge of the consequences of fixation on immunorecognition is indicated via the variations reported regarding the exact same antigen stained in DU145 cells compared to SKOV-3 cells (Otali et al.
