The 2007 Once-a-year Scientific Session from the BSC centered on types of fixation and results of fixation on immunohistochemistry as predicted by these versions. The only model of fixation offered by Dr. Bogen evaluated single epitopes of diagnostic antigens, i.e., antibodies. Slightly additional advanced styles offered by Dr. O’Leary evaluated the consequences of fixation on uncomplicated proteins, RNA, and DNA, and one of the most complicated product presented by Dr. Otali permits evaluation of the consequences of fixation on intact mobile preparations. The complexity of the situation of the effects of fixation on immunorecognition is indicated with the variances reported regarding the exact antigen stained in DU145 cells versus SKOV-three cells (Otali et al.
