TMB can be used in immunohistochemistry. Kirkegaard & Perry
Laboratories (KPL) are offering a TMB substrate (TrueBlue), which is
optimized for use with cellular preparations, and can also be used for
immunoblotting. To avoid fading during wash, KPL recommend use of Tris
HCl or PBS. If fading occurs during dehydration, please omit alcohol
and use graded acetone. Use only non-aqueous mounting media.
