The 2007 Yearly Scientific Session with the BSC focused on types of fixation and results of fixation on immunohistochemistry as predicted by these products. The only product of fixation presented by Dr. Bogen evaluated single epitopes of diagnostic antigens, i.e., antibodies. A little bit far more sophisticated designs offered by Dr. O’Leary evaluated the results of fixation on uncomplicated proteins, RNA, and DNA, and one of the most intricate product presented by Dr. Otali permits evaluation of the effects of fixation on intact mobile preparations. The complexity of the situation of the effects of fixation on immunorecognition is indicated with the discrepancies reported in regards to the exact antigen stained in DU145 cells compared to SKOV-3 cells (Otali et al.
