Optical dephasing in red fluorescent protein

Autor: Silvia Völker, S. Bonsma, R. Purchase, J. Gallus, F. Konz

Publikováno v: Journal of Luminescence. 108:153-157

The excited state dynamics of the red fluorescent protein DsRed have been studied by spectral hole-burning at low temperature. The homogeneous line width Γhom of the S1←S0 0–0 transition of the red (R-) form was obtained from MHz-resolution hole

Light-induced conformational changes and energy transfer in red fluorescent protein

Autor: Silvia Völker, F. Konz, S. Bonsma, J. Gallus, R. Purchase

Publikováno v: Journal of Luminescence. 107:203-212

Reversible conformational changes have been photo-induced in the red fluorescent protein DsRed at low temperature by wavelength-selective laser irradiation. We have found two new fluorescent forms: a shifted-red (SR-) and a new green (G′-) form tha

Spectral hole burning and optical dephasing in disordered crystals – Pr3+:LiNbO3 and Pr3+:Sr.6Ba.4Nb2O6 (SBN)

Autor: Rufus L. Cone, Roger M. Macfarlane, Y. Sun, F. Konz

Publikováno v: Journal of Luminescence. 86:311-315

We have measured the homogeneous line widths of the 3 H 4 (1) to 1 D 2 (1) transition of Pr3+ ions in the ferroelectric, photorefractive crystals, strontium barium niobate and lithium niobate in the range 1.3–3 K using spectral hole burning and pho

Laser spectroscopic techniques at low temperature, such as fluorescence line-narrowing and hole burning, enable an increase of spectral resolution by a factor of 103–105 compared to conventional spectroscopy at room temperature. With these methods,

IL-21 activates both innate and adaptive immunity to generate potent antitumor responses that require perforin but are independent of IFN-gamma

IL-21 is a key factor in the transition between innate and adaptive immune responses. We have used the cytokine gene therapy approach to study the antitumor responses mediated by IL-21 in the B16F1 melanoma and MethA fibrosarcoma tumor models in mice

Publikováno v: Neuroscience letters. 332(3)

Experimental autoimmune encephalomyelitis (EAE) is an inflammatory disease of the central nervous system (CNS) that can be induced in susceptible mice by the transfer of autoreactive T cells that recognize myelin basic protein (MBP). The onset and su

Summary form only given. Congruent lithium niobate has a disordered, lithium-deficient structure in which Nb/sub Li/ antisites provide charge compensation for lithium vacancies. The disorder is produced by departures from stoichiometry, which play an
