Merck Immobilon Western HRP Chemiluminescence Substrates

Horseradish peroxidase (HRP) catalyzes the oxidation of luminol in the presence of peroxide, releasing photons (chemiluminescence) that are captured on x-ray films or by CCD cameras. Most HRP substrates are plagued by quickly decaying signal and short shelf life, but Luminata substrates are formulated differently to include stabilizing reagents.

• Consistent results with less pipetting error

The stabilizers added to Luminata substrates:

• Prevent spontaneous oxidation of luminol by peroxide in the absence of HRP
• Enhance the stability of both the luminol and peroxide, ensuring that Luminata substrates are stable for one year in their premixed format
• Stabilize, strengthen, and prolong the chemiluminescence signal once HRP starts to catalyze oxidation

Three different sensitivities for a range of detection needs:

• Immobilon Classico premixed reagent for everyday detection needs
• Immobilon Crescendo premixed reagent for detection in the picogram range
• Immobilon Forte premixed reagent for detection in the femtogram range
