Technical Information

Vector Blue is both chromogenic and fluorescent. Sections stained with the Vector Blue substrate can be dehydrated, cleared, and permanently mounted; however, non-xylene clearing agents and non-xylene based mounting media (such as VectaMount®, H-5000) must be used because the reaction product is soluble in xylene. Vector Blue can also be used on blots in applications such as ELISPOT, singly or in combination with a peroxidase substrate such as AEC. This kit contains stock solutions in convenient dropper bottles.
