General description

DAB (3,3′-Diaminobenzidine Tetrahydrochloride) Liquid Substrate Dropper System has been developed for use in immunohistology and immunoblotting procedures as a precipitating substrate for the detection of peroxidase activity. DAB is the immunohistology substrate of choice because it produces an intense brown stain that is easily observed. The end product is resistant to alcohol, therefore, a variety of counterstains and mounting media can be used with the DAB Liquid Substrate Dropper System. DAB Liquid Substrate Dropper System provides all of the chromogen and buffer/peroxide solutions needed to produce a fast and convenient DAB substrate solution.

Application

3,3′-Diaminobenzidine (DAB) Liquid Substrate Dropper System has been used as a developer in immunohistogical examination.

Caution

Stable at least one year at 2-8 °C.

Quantity

Each DAB liquid substrate dropper system will provide ten individual application dropper bottles of 10 mL of a fast and convenient DAB substrate solution.

Immunoblotting techniques are widely used for detection of antigen immobilized on nitrocellulose membranes. There are many immunolabeling methods and staining methods available to disclose the presence of antigen in such techniques. Five common staining methods each for alkaline phosphatase and

Three metallic ions, NiCl2, CoCl2, and CuSO4, were found to modify the color of the normally brown diaminobenzidine (DAB) reaction. The colors ranged from purplish blue (NiCl2), dark blue/bluish black (CoCl2), to greyish blue (CuSO4). We have found that the

For the bioanalysis of therapeutic monoclonal antibodies in biological matrices, immunoassays--especially enzyme-linked immunosorbent assays (ELISAs)--are the most widely used techniques. Although ELISAs are very sensitive, the obtained sensitivity is not always sufficient. In this study, we have investigated the possibilities
