DAB (3,3′-Diaminobenzidine) is a derivative of benzene. It is most often used in immunohistochemical (IHC) staining as a chromogen. It is also used in in situ hybridization (ISH) and sometimes in dot blots and in western blotting. In DAB staining, DAB is oxidized by hydrogen peroxide in a reaction … See more Compared to fluorescent methods used for IHC, chromogenic detection, such as DAB staining, is typically more sensitive due to the enzymatic amplification used with DAB staining and similar … See more A disadvantage of DAB is that it reacts slowly with hydrogen peroxide, even without the presence of a peroxidase enzyme. This means that once the DAB is combined with … See more For complete protocols for immunostaining using DAB, please see our collection of validated IHC protocolsbased on our own experience with antibody validation. A lot of DAB staining uses … See more WebPrepare DAB by adding 2 drops of DAB-chromogen per 1ml DAB-substrate buffer and mix; Staining reaction: Cover tissue with prepared DAB chromogen solution, incubate approximately for 10min. to allow for proper brown colour development. Wash slides thoroughly in H2O; Counterstain with hemalaun for 2min; Wash slides in H2O
