WebRoutine fixation in neuroscience with buffered 4% paraformaldehyde is typical but there are a variety of fixatives and fixation methods. Fresh tissue can be sectioned and post fixed but for good retention of labile protein molecules (such as neurotransmitters), transcardial perfusion with a paraformaldehyde-based fixatives is preferred. Web1) Paraformaldehyde 2) Acetone 3) 1:1 solution of acetone:alcohol (methanol or ethanol) Fix with the fixative for 15 min, at room temperature. Rinse 3–4 times in PBS. For acetone fixation, air dry completely for 30 min under airflow. Continue with the immunohistochemical staining protocol.
