WebThe visualization of glycogen deposits in cells and tissues is important for studying glycogen metabolism as well as diagnosis of glycogen storage diseases. Evidence suggests that the demonstration of glycogen can better be enhanced by factors such the choice of fixative and temperature during fixation. WebGlycogen is unaffected directly but is either physically trapped within precipitated protein or, if it is bound to protein, is preserved along with the protein as it is fixed. This preservation of glycogen is striking enough that picric acid fixation is recommended when glycogen is of special interest, particularly if it is used in conjunction ...
