Application
SIGMAFAST™ OPD (o-Phenylenediamine dihydrochloride) tablets have been developed for use as a soluble substrate for the detection of peroxidase activity in enzyme immunoassays (EIA). OPD is the EIA substrate of choice as it exhibits high sensitivity. EIA applications utilizing OPD may be read in timed assays or stopped with dilute acid solutions for delayed readings.
SIGMAFAST OPD has been used in saliva- virus-like particles (VLP) binding assay.[1] It has also been used to develop enzyme linked immunosorbent assay (ELISA) plates for the detection of rituximab in rat serum samples.

Features and Benefits
SIGMAFAST™ OPD Tablets require no additional buffers or steps to prepare an active substrate solution.
Preparation Note
Each tablet set dissolved in 20 mL deionized water yields a ready-to-use buffered solution containing OPD and urea hydrogen peroxide.
One OPD tablet and one urea hydrogen peroxide/buffer tablet, dissolved in 20 ml of water, provides 20 ml of ready-to-use substrate. When the tablet is dissolved in this manner, the final concentrations will be 0.4 mg/ml OPD, 0.4 mg/ml urea hydrogen peroxide, and 0.05 M phosphate-citrate, pH 5.0. Tablets are individually packaged in foil packets.

Can I make the solution in large quantity and keep it in the fridge? Or should the solution be used right away because of its light sensitivity?
1 answer-
The Substrate Solution is light-sensitive and should be protected from direct sunlight or UV sources in a
tightly capped amber bottle. For best results, the Substrate Solution should be used within one hour.The Product Information Sheet is available for additional details:
