WebOct 1, 2013 · Fixing ensures that your cell structures stay intact and that your antigens are immobilized. Ideally, fixation would also still permit unfettered access of your antibodies to your antigens. However, as you will learn in this primer, this is often a game of give and take. WebMethanol Permeabilization Step: Cover specimen to a depth of 2-3 mm with ice-cold 100% methanol and incubate for 10 minutes on ice or at 4°C. Rinse three times in 1X PBS. Block specimen in Blocking Buffer for 60 min. While blocking, prepare primary antibody in Antibody Dilution Buffer (see product website for recommended dilution range).
