Cat#: 30014
DAB (3,3'-Diaminobenzidine) leads to the formation of a dark-brown precipitate at the location of the target antigen. The precipitate is insoluble in aqueous and organic solvents allowing the use of commonly known mounting media. This chromogen/substrate system is especially useful when a high contrast between the chromogen and counter stain is desired. Compared to standard DAB staining kits the HISTOLS®-DAB Chromogen/Substrate System gives a darker brown color and a higher sensitivity.
Cat#: 30015
HISTOLS ® Resistant AEC Chromogen/Substrate System was developed for immunohistochemical staining procedures using horseradish peroxidase (HRP) labeled secondary antibody. AEC (3-amino-9-ethylcarbazol) leads to the formation of reddish-brown precipitate at the location of the target antigen. The precipitate is insoluble in aqueous and organic solvents, which allows the use of commonly known mounting media.
