An analysis of a peak for PpIX in the cells was performed using a fluorescence microplate reader. The measurement showed that PpIX has a peak of excitation wavelength at 410 nm and emission wavelength at 606 nm in the culture medium (HamF12 + 4% HCl). Volumes of PpIX in the medium after 4 hour culture of the cells were measured with a microplate reader using filter set of excitation wavelength 400/30nm and emission wavelength 620/40nm. However the cells did not secrete significantly PpIX during 4 hour incubation in this culture system, addition of quail plasma to the medium resulted in significantly higher secretion. A cultivation system in this study is able to use for the study on the mechanism of the secretion of eggshell pigment, PpIX from Japanese quail shell gland epithelial cells.展开更多
