EcoMount is a fast-drying, optically clear, permanent mounting medium. This polymer-based mounting medium does not contain hazardous reagents such as xylene, toluene or benzene as its base solvent. EcoMount is designed especially for the permanent preservation of horseradish peroxidase, alkaline phosphatase and Qdot (quantum dot nanocrystals) immunofluorescent techniques. EcoMount permits long-term storage of slides with chromogens such as Warp Red, Vulcan Fast Red and Ferangi Blue. It can also be used with DAB and other non-soluble chromogens. EcoMount dries quickly and retains excellent refractivity. EcoMount is compatible for use on automatic coverslipping machines.
