Counterstain/Substrate Compatibility Table
This table is designed as a reference to determine the optimal counterstain/substrate combination for your application. Considerations should be given to tissue type, antigen unmasking protocol and other detection parameters to achieve the desired staining intensity.

* This substrate shows a slight decrease in sensitivity following the methyl green protocol. This decrease can be minimized by reducing the heat incubation and acetone rinse times in the methyl green protocol.
** Substrate dissolves in acetone wash.
*** A slight color change in ImmPACT NovaRED and Vector NovaRED reaction product may be seen using methyl green.
