3,3′-Diaminobenzidine (DAB) Liquid Substrate Dropper System
3,3′-Diaminobenzidine (DAB) Liquid Substrate Dropper System, CAS 7411-49-6, is a specialised reagent for peroxidase detection in biological samples. This liquid formulation, supplied in a convenient dropper system, is primarily utilised for immunohistochemistry (IHC) staining of tissue sections. It provides a reliable method for visualising peroxidase activity, crucial for diagnostic and research applications in pathology and molecular biology.
Immunohistochemistry (IHC)
This DAB liquid substrate is specifically designed for use in IHC staining protocols. It allows for the sensitive and specific detection of peroxidase-labelled antibodies in fixed tissue sections.
Peroxidase Detection
The system serves as a chromogenic substrate for peroxidase enzymes. Upon enzymatic reaction, it forms a brown precipitate at the site of enzyme activity, enabling visualisation.
Blotting Applications
While primarily for IHC, DAB substrates can also be adapted for certain blotting techniques where peroxidase detection is required.
Histochemistry
Used in general histochemical staining to identify and localise peroxidase activity within cellular and tissue structures.
