Fixation with paraformaldehyde
WebThere are 4 major groups of fixatives, namely the aldehydes, oxidizing agents, alcohol based fixatives and the metallic group of fixatives. The aldehydes (formaldehyde, glutaraldehyde) and oxidizing agents (osmium tetraoxide, potassium permanganate) acts by cross-linking proteins.
