Expanding PQQ\u27s Biosensor Applications: The Effects of Illumination on the Reactivity of PQQ.

, 2001
2,7,9-Tricarboxyl-1H-pyrrolo[2,3-f]quinoline-4,5-dione, commonly known as PQQ or pyrroloquinoline quinone, functions as a redox cofactor in bacterial methanol and glucose dehydrogenases. These enzymes require a divalent metal ion for activity. This study

Effect of PQQ on RANKL-induced osteoclast differentiation.

, 2013
(A) BMMs were cultured for 4 days with M-CSF (30 ng/ml) and RANKL (50 ng/ml) in the presence of varying concentrations of PQQ. Arrows indicate the osteoclast. (B) TRAP-positive cells were counted as osteoclasts.
