WebDAB (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 typically catalyzed by horseradish peroxidase ... WebA compound microscope is defined as the type of microscope that has more than one lens. It has a combination of lenses and two optical parts known as an objective lens and an eyepiece or ocular lens. The magnifying power of the compound microscope is given as: m = D f o × L f e Where, D is the least distance of distinct vision
