Liquid DAB+ is a 2-component system for Immunohistochemistry Visualization developped by Dako.
Liquid DAB+ is a high sensitivity substrate-chromogen system for use in peroxidase-based immunohistochemical staining methods. DAB (diaminobenzidine) forms a very stable, brown end-product at the site of the target antigen. DAB may be used together with mounting fluids containing organic solvents.
