What is the solubility of p-Phenylediamine, Product P6001?
This product is soluble in ethanol at a concentration of 50 mg/mL, with heating. A clear red to brown solution is observed.
For what applications is p-Phenylediamine, Product P6001, used?
This is an antifade reagent that is used as a fluorescent stabilizer. Do not confuse the p-phenylenediamine with o-phenylenediamine, which is used as a peroxidase substrate in ELISA procedures.
What is the working concentration for p-Phenylediamine, Product P6001, when used as an antifade agent?
J. Immunological Methods, 43, 349 (1981) describes a solution that will reduce the fading of fluorescent materials. The recipe for this solution is: "Add 10 mL of phosphate-buffered saline (0.01 M PO4, pH 7.4 in 0.15 M NaCl) containing 100 mg of p-phenylenediamine to 90 ml of glycerol. The final pH should be adjusted to approximately 8.0 with 0.5 M carbonate-bicarbonate buffer (pH 9.0)."
