Often a two step fixation is preferred with formaldehyde that penetrates faster but fixes less firmly, followed...

WebDehydrating/denaturing fixatives, such as methanol, displace water around cellular macromolecules, resulting in their denaturation and precipitation in situ. Denaturation of the target protein may expose normally buried epitopes, making this approach advantageous for some antibodies. WebFixation by alcohols works by removing the hydrate cover, causing the proteins to collapse and re-fold in the process, rendering them insoluble. Methanol is merely the fastest …
