WebIn TEM , myelin periodicity is reduced to around 120 Å (as compared to the 170 Å in X-ray diffraction on fresh myelin), probably due to dehydration and fixation . TEM can provide excellent high-resolution images of myelin, but as with all TEM imaging, samples preparation can represent a major source of problems [ 8 ]. Web29 jun. 2011 · E and F, Alignment of myelin sheath revealed differences in myelin periodicity. Periodicity was measured as the mean distance between two major dense lines from at least five randomly chosen myelin sheaths per genotype and area. All data are mean ± SEM.
