"The colorimetric assay procedure of Prescott and Jones has been modified to make the standard curve more consistently linear. Improved results are obtained when the assay tubes are exposed to yellow light at an intensity of 45-50 footcandles (480-540 lux) during color development. Somewhat longer incubation times are required for color development with yellow light"--Abstract. Colorimetric analysis. Allantoin. Optical measurements. Analyse colorimétrique. Allantoïne.
