For example, neurofilament
staining will highlight entrapped axons in the middle of an infiltrative tumor.
The sections from lowest PMI (ID B-183) and longest PMI (ID T-144) were immunostained with antibodies to GFAP (Glial marker, 1:200) and neurofilament
(axonal marker, 1:100) to note if there is any difference in staining character.
But in their mice at least, says study leader Jean-Pierre Julien of McGill University in Montreal, the neurofilaments
indeed play the villain.
Additionally, 5-[micro]m sections were taken from the paraffin blocks and stained using antibodies against Melan-A (prediluted, monoclonal, catalog number 790-2990; Ventana Medical Systems, Tucson, Arizona), S100 protein (prediluted, polyclonal, catalog number 760-2523; Ventana Medical), and neurofilament
(prediluted, clone 2F11, monoclonal, catalog number 760-2661; Ventana Medical) following the manufacturer's protocols in a BenchMark XT automated slide stainer (Ventana Medical).

The surgical specimen was tested for S- 100 protein, neurofilaments
, neuron-specific enolase, CD56, CD57, and synaptophysin (table).

11) Merkel cell carcinoma expresses a wide range of neuroendocrine markers such as neurofilaments
, neuron-specific enolase, chromogranin, synaptophysin (Figure 3), bombesin, somatostatin, vasoactive intestinal peptide, and proconvertases PC1/ PC3 and PC2.
Immunohistochemical tests were positive for neuron-specific enolase, immunoreactive neurofilaments
, CD57 (Leu-7), and synaptophysin.

, neurotubules and, occasionally, Schwann-like cells can be seen.
