Ultrastructural characterisation of the M protein in nerve biopsy of patients with POEMS syndrome.


To learn more about the mechanisms of nerve lesions in POEMS syndrome, nerve specimens from four patients were studied with an immunogold method at the ultrastructural level to detect and localise the M protein in the different nerve compartments. An indirect immunolabelling technique was applied on 4% PFA fixed and LR White embedded nerve specimens… (More)
