[Molecular consequences of fixation and tissue processing: the examples of nucleic acids and proteins]. / Les conséquences moléculaires de la fixation et de l'inclusion: exemple des acides nucléiques et des protéines.

The scientific usefulness of the molecular data obtained from tissue analysis is related directly to the quality of the tissue specimen. The most ideal tissue specimen is the one that carries a complete and unaltered representation of the tissue in vivo. The aim of this review is to provide an overview of the effects of fixation and tissue processing on the content and integrity of nucleic acid and proteins.
