Excitation lifetime of photosynthetic pigments in vitro and in vivo.
A quantitative assay for the number of chromophores on a chromoprotein; its application to phycoerythrin and phycocyanin
Abstract A non-destructive assay for the number of chromophore groups, R , associated with a chromoprotein ( e.g. phycoerythrin, phycocyanin) and the molar extinction coefficient e m can be made with… Expand

PARAMAGNETIC RESONANCE OF CHLOROPHYLL CRYSTALS AND SOLUTIONS
Fluorescence changes during chlorophyll formation in Euglena gracilis (and other organisms) and an estimate of lamellar area as a function of age.
SYNOPSIS. In the present study, we show for various photosynthetic organisms in the mature state the diversity which exists in the relative fluorescence intensities of the aggregate and monomer of… Expand
