Chromogen / Substrate Systems
HISTOLS®- DAB
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.
HISTOLS®- Resistant AEC
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.
HISTOLS®- Resistant AP Red
Cat#: 30019
HISTOLS®-AP Red Chromogen/Substrate System was developed for immunohistochemical staining procedures and will produce red colored deposit upon reaction with alkaline phosphatase at the site of the target antigen. The precipitate is insoluble in aqueous and organic solvents, which allows the use of commonly known mounting media.
