Two-photon-induced fluorescence from the phycoerythrin protein.
نویسندگان
چکیده
Two-photon-induced fluorescence is observed from the photodynamic phycobiliprotein phycoerythrin. Temporal, spectral, and intensity-dependent properties of the two-photon-induced fluorescence emission from phycoerythrin excited by a 1.06-mum laser beam are reported. The measured two-photon absorption cross section of phycoerythrin is an order of magnitude larger than that of Rhodamine 6G. The potential applications of phycobiliproteins for two-photon-induced fluorescence for microscopy of three-dimensional biological samples and three-dimensional optical memory are discussed.

Fluorescent phycobiliprotein conjugates for analyses of cells and molecules
The synthesis of a novel class of reagents for fluorescence analyses of molecules and cells is reported. These compounds consist of a highly fluorescent phycobiliprotein conjugated to a molecule having biological specificity. Phycoerythrin-immunoglobulin, phycoerythrin-protein A, and phycoerythrin-avidin conjugates were prepared. These conjugates bind specifically to beads containing a covalent...
متن کاملThe Fluorescence Spectra of Red Algae and the Transfer of Energy from Phycoerythrin to Phycocyanin and Chlorophyll
1. The fluorescence spectra of the alga Porphyridium have been recorded as energy distribution curves for eleven different incident wave lengths of monochromatic incident light between wave lengths 405 and 546 mmicro. 2. In these spectra chlorophyll fluorescence predominates when the incident light is in the blue part of the spectrum which is strongly absorbed by chlorophyll. 3. For blue-green ...
متن کاملPhycobilisomes and Isolated Phycobiliproteins. Effect of Glutardialdehyde and Benzoquinone on Fluorescence
The fluorescence of the biliproteins C-phycocyanin from Spirulina platensis, B-phycoerythrin from Porphyridium cruentum and of isolated whole P. cruentum phycobilisomes is quenched in the presence of glutardialdehyde (GA) or benzoquinone (BQ). The kinetics of fluorescence decrease thus induced is biphasic. If GA is used as a quencher, the fluorescence can be recovered at 77 K. Contrary to the G...
متن کاملLaser-induced fluorescence emission (L.I.F.E.): in situ nondestructive detection of microbial life in the ice covers of Antarctic lakes.
Laser-induced fluorescence emission (L.I.F.E.) images were obtained in situ following 532 nm excitation of cryoconite assemblages in the ice covers of annual and perennially frozen Antarctic lakes during the 2008 Tawani International Expedition to Schirmacher Oasis and Lake Untersee in Dronning Maud Land, Antarctica. Laser targeting of a single millimeter-scale cryoconite results in multiple ne...
متن کاملResonance Energy Transfer Between Luminescent Quantum Dots and Diverse Fluorescent Protein Acceptors.
We characterized the resonance energy transfer interactions for conjugates consisting of QD donors self-assembled with three distinct fluorescent protein acceptors: two monomeric fluorescent proteins, the dsRed derivative mCherry or yellow fluorescent protein and the multi-chromophore b-phycoerythrin light harvesting complex. Using steady-state and time-resolved fluorescence, we showed that non...
