Considering the significant quenching of fluorescence by manganese (Mn), it is not suitable for the assay. Instead, the use of MgCl2 (up to 1 mM) is suggested as it offers less interference. Additionally, DTT can be used up to 1 mM.

General description
Pyrophosphate (PPi) is produced by a number of biochemical reactions such as ATP hydrolysis,[1] DNA and RNA polymerizations, cyclic AMP formation, and the formation of fatty acid-coenzyme A esters. It is hydrolyzed by inorganic pyrophosphatase. PPi is present in the blood and in the extracellular matrix of tissues.[1]
Suitability
The Pyrophosphate Assay Kit provides a simple and direct microplate assay procedure for measuring pyrophosphate in a variety of samples.
Principle
The pyrophosphate concentration of a sample is determined by the use of a unique fluorogenic pyrophosphate sensor in which the presence of pyrophosphate results in the production of a fluorescent product (λex =316/λem = 456 nm) proportional to the pyrophosphate present. This assay is simpler and more robust than traditional enzyme-based methods and is ideal for screening enzyme activity or enzyme inhibitors.

Any challenges encountered with decreases in fluorescence due to buffer components in the assays, such as manganese (1 mM), DTT (5 mM), and the combination of manganese with a reducing agent (both BME and DTT)? It seems that the signal is significantly reduced, if not entirely abolished, when these components are included in the buffer, even with substantial amounts of the PPi standard.
