Chromogens

From:Patricia Karlisch <PKARLISCH@geisinger.edu>

Dear Histonetters:
  We would like to do some double staining and are looking for an alternate chromogen to stain with. We use the standard DAB and Nova Red. The nova red that we are currently using is giving a washed out reddish color.  Do any of you know of a chromogen  (and its supplier) that gives a vivid red color?   Can you recommend anything else that will not interfere with endogenous melanin or hemosiderin pigments.  Thank you in advance.
