Diaminobenzidine substrate kit
The Diaminobenzidine substrate kit is a laboratory reagent used in immunohistochemistry and enzyme-linked immunosorbent assays (ELISA) to detect the presence of specific proteins or antigens in biological samples. The kit contains a stable diaminobenzidine solution that produces a brown color upon reaction with an enzyme-labeled detection system. This colorimetric reaction allows for the visualization and localization of the target analyte within the sample.

Immunohistochemical Analysis of Rat IgM
Immunofluorescence and Immunohistochemistry Protocols
For IHC analysis, paraffin-embedded tissues were fixed on slides and then blocked with 5% donkey serum (Gibco, U.S.) for 45 min, followed by incubation with anti-pNF90-Ser382 antibody (Youke, Shanghai, China) or anti-Ki67 antibody (Abcam, U.K.) overnight at 4 °C. The horseradish peroxidase-conjugated secondary antibody was used and the Diaminobenzidine Substrate Kit (Sigma, U.S.) was applied for signal detection. All tissue sections were counterstained with hematoxylin (Sigma, U.S.).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
