CITOQUIMICA E HISTOQUIMICA PDF

En la prctica se emplea la palabra para designar el mtodo junto con el auxilio de los microscopios pticos MO y electrnico ME. Esta tcnica permite la identificacin y localizacin de compuestos o radicales qumicos en las clulas y tejidos. Esto se consigue provocando reacciones que dan productos insolubles que son coloreados o electrodensos y visibles por el MO y el ME. Este problema se resuelve insolubilizando los compuestos que van a ser estudiados por medio de la fijacin del tejido. Los fijadores ms utilizados son: - Formaldehdo para el MO.
