Thanks very much for your inquiry John. The Vector NovaRED peroxidase 
substrate, similar to our other unique peroxidase and alkaline 
phosphatase substrates (Vector VIP, Vector SG, Vector Red, Vector Blue, 
etc), is a proprietary formulation. As briefly described in our previous 
correspondence, the reaction is similar to that of DAB. However, unlike 
DAB, none of the reagents in the Vector NovaRED substrate are known or 
suspected carcinogens. We are unaware of any specific literature 
describing the chemistry of this particular product.

We hope this information is of some interest.

Sincerely,
