RE: Romulin AEC
We have some brief experience with Romulin AEC. Indeed this type of AEC can
be mounted up successfully with organic mounted media such as DEPEX, etc.
However, it disappears after a couple of weeks when mounting with
VectaMount, an organic but non-xylene or alcohol containing mounting medium.
The efficiency/sensitivity of the chromogen is nearly equal to our protocol
for "regular" AEC (this protocol usually yields more reaction product than
most commercially available AEC kit systems)
There is also a possibility to boost the efficiency/sensitivity by adding
twice the amount of Romulin AEC chromogen.
A disadvantage of Romulin AEC is the color of the reaction product. In
comparison with nice brick-red of "regular"AEC, Romulin AEC yields a
brown-reddish color that is not so suitable for double staining with a blue
color for example.
