Product Description

10-Acetyl-3,7-dihydroxyphenoxazine (N-Acetyl-3,7-dihydroxyphenoxazine), which has been marketed under the name Amplex® Red, is regarded as the best fluorogenic substrate for peroxidase because it is highly specific and stable. The substrate itself is nearly colorless and nonfluorescent until it is oxidized by H2O2 in the presence of horseradish peroxidase (HRP) to become the highly red fluorescent resorufin. High purity resorufin (10062) is also available from Biotium to be used as a standard.
