The substrate-chromogen is the final step in the detection portion; it enables the antibody antigen complex to be viewed under the light microscope. This occurs because HRP Mulberry acts as an electron donor in the presence of the enzyme horseradish peroxidase; HRP Mulberry gets oxidized and produces a dark purple color tinted with red at the site of the target antigen or nucleic acid. | HRP Mulberry forms a permanent record of the stain results when coverslipped with a ChromoProtector (BSB 0151-0156) and organic based mounting medium, such as PermaMounter (BSB 0094-BSB 0097) or XyGreen PermaMounter (BSB 0169 – BSB 0174). It can also be mounted with media such as AquaMounter (BSB 0090-BSB 0093) but the stain will fade and crystalize within 24 hours."}]}]}
