University of Groningen FLUORESCENCE OF HOUSEFLY VISUAL PIGMENT

University of Groningen FLUORESCENCE OF HOUSEFLY VISUAL PIGMENT

The fluorescence of housefly photoreceptors was studied in viuo by using the deep pseudopupil technique. Whereas the rhodopsin R490 of the peripheral retinular cells fluoresces negligibly the metarhodopsin M580 fluoresces distinctly in the red. The newly discovered metarhodopsin M’ is produced by intense blue light and can be reconverted into rhodopsin by intense long wavelength light. M’ also ...

University of Groningen Photoreceptor Redox State Monitored In Vivo by Transmission and Fluorescence Microspectrophotometry in Blowfly Compound Eyes Tinbergen, Joost; Stavenga, Doekele

The transmission and fluorescence of the compound eye of living, intact blowflies Cuiliphoru erythrocephala, mutant chalky, were studied microspectrophotomettically. Transmission spectra were recorded under four conditions. The fly was either in the normal air environment or in a nitrogen atmosphere, and in both cases the investigated eye was adapted to red and blue light. respectively. The abs...
