Home / Products / Enzyme Substrates / Chemiluminescent/ Chemifluorescent Substrates Chemiluminescent/ Chemifluorescent Substrates The DuoLuX™ Chemiluminescent/Chemifluorescent Substrate is a unique formula based on acridan chemistry that produces both a strong chemiluminescent and fluorescent signal. The half-life of luminescent emission exceeds that of many other luminescent substrates. Reacted DuoLuX™ Substrate luminesces in the blue range with a peak emission at 453 nm. This emitted light can be captured by film or with an imager. The fluorescence excitation maximum is a 405 nm, but other wavelegths (254 nm and 365 nm) can also be used. Maximum fluorescent emission occurs at 453 nm. 2 Showing Position Name Catalog Number Price View as: List Grid Show 30 60 120 DuoLuX Chemiluminescent and Fluorescent Alkaline Phosphatase (AP) Substrate Catalog Number: SK-6605 Unit Size: 100 ml Add to Wishlist | Add to Compare As low as: $200.00 $250.00 Add to Cart DuoLuX Chemiluminescent and Fluorescent Peroxidase (HRP) Substrate Catalog Number: SK-6604 Unit Size: 200 ml Add to Wishlist | Add to Compare As low as: $208.00 $260.00 Add to Cart 2 Showing Position Name Catalog Number Price View as: List Grid Show 30 60 120 Didn't find what you were looking for?
