An image showing a section of rat spinal cord stained with Mouse monoclonal antibody to Ubiquitin C Terminal Hydrolase 1 [BH7] M-1407-100 (red) and Rabbit polyclonal antibody to neurofilament H R-1388-50 (green). The large cells are a-motorneurons and Ubiquitin C Terminal Hydrolase 1 (UCHL1) fills the cytoplasm of their perikarya and dendrites. The neurofilament NF-H antibody binds primarily to phosphorylated axonal forms of NF-H, and so stains axons coursing between the large motor neurons.
