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