The use of 3,3',5,5'-tetramethylbenzidine as a peroxidase substrate in microplate enzyme-linked immunosorbent assay

J Immunoassay. 1987;8(1):29-41. doi: 10.1080/01971528708063053.

Abstract

The assay conditions for the use of 3,3',5,5' tetramethylbenzidine (TMB) in microplate enzyme-linked immunosorbent assay are described. TMB is a safe (non-mutagenic) chromogen that is more sensitive than OPD as a substrate for horseradish peroxidase. We describe the optimum storage and assay conditions for this chromogen.
