Image of a mouse cerebellum by Immunofluorescence. The section was stained with M-2112-50, Neurofilament light polypeptide (NF-L), Clone 7D1, Mouse mAb, (green, 1:5000), and co-stained with product chicken antibody to FOX2, (red, 1:2,000) IF Method: Following transcardial perfusion of mouse with 4% paraformaldehyde, brain was post-fixed for 24 hours, cut into 45 µm sections, and free-floating sections were stained. The NF-L antibody labels dendrites and axons of neuronal cells, predominantly axons in white matter and basket cell axons associated with Purkinje cells. The FOX2 antibody reveals protein expressed in a subset of neurons, including Purkinje cells.
