Fluorescence assay. Fluorescence intensity over time of 2 μmol/L purified LR and urine collected during phototherapy, each mixed with UnaG mixture (see Methods in the text) and then exposed to blue light. In both samples, the fluorescence intensity representing the UnaG–ZZ-BR complex increased with duration of exposure and plateaued at 60–75 min. LR, lumirubin; ZZ-BR, ZZ-bilirubin.
