TrueBlue is a highly sensitive chromogenic substrate for visualization of horseradish peroxidase-labeled reporter reagents


  • Free of known carcinogens
  • Recommended for detection of the least abundant marker
  • High sensitivity


TrueBlue is up to 100 times more sensitive than DAB and it is free of known carcinogens. Strong blue reaction product provides excellent contrast with DAB and other substrates. HistoMark TrueBlue provides the most sensitive means available to detect peroxidase-labeled conjugates. Because of its high sensitivity, TrueBlue is recommended for detection of the least abundant marker. TrueBlue is alcohol and xylene insoluble.
