Summary: 3, 3´ Diaminobenzidine (DAB) is a commonly used chromogen for histological staining. In the presence of peroxidase enzyme, DAB produces a brown precipitate that is insoluble in alcohol and xylene. Peroxidase catalyzes hydrogen peroxide oxidation of substrate DAB. This SOP provides instructions to prepare four different formulations of DAB. DAB for Immunohistochemical staining (IHC), DAB for Acetylcholinesterase (AChE) Staining, Nickel Enchanced DAB for Biocytin staining, and DAB for Biocytin staining.Note: Research reported in this publication was supported by the National Institute Of Mental Health of the National Institutes of Health under Award Number U19MH114830.

Summary: This protocol is used to generate accurate digital representations of neuron morphologies from a variety of brain regions and species. Each reconstruction captures the positions and thicknesses of the soma, dendrites and axon of a biocytin-filled cell within a slice of brain tissue. To generate the reconstruction we use an image stack containing ~200-700 serial 2D images that captures the full extent of the cell within the slice. We use the Vaa3D (Terafly) program with a Kazom’s Mozak user interface (Mozak for short) to visualize the 2D images in 3D. Once the stack is loaded in Mozak, our reconstruction is generated by placing nodes in 3D space. The placement of these nodes is dependent on the signal in the images. Our final output, an SWC text file (.swc format), contains many thousand rows. Each row contains a node ID, an x, y, z coordinate, radius value, neurite type, and parent node ID. After tracing is complete, we preform post processing to provide radius values, check for errors and consistency then the SWCs are uploaded into our Laboratory Information Management System.Note: Research reported in this publication was supported by the National Institute Of Mental Health of the National Institutes of Health under Award Number U19MH114830.
