  • Chemical fixation protocol ( Protocol )

    "To be able to view a biological sample in the electron microscope it must first be stabilized or 'fixed' in a way that the ultrastructure of the cells or tissue remain as close to the living material as possible. The choice of fixative depends on the purpose of your study. It should be noted that, even though standard protocols can be sufficient for many purposes, finding the right fixation conditions is often a matter of trial and error. "

  • Embedding in resins protocol ( Protocol )

    "The routine method for examining biological samples in TEM is to embed the material in plastic and cut ultrathin (~60-80nm) sections. The choice of resin depends on the type of sample and the purpose of your study. Listed below are some of the more commonly used ones. "
