A fluorescence polarization flow cytometer [PDF]

open access: yesCytometry, 1980
AbstractThe effect of mitogens on the degree of polarization of the fluorescence from viable human lymphocytes, labeled with fluorescein, have been reported to be different in cells from subjects with malignant disease as compared with those from healthy donors.

Picosecond time-resolved fluorescence of phycobiliproteins [PDF]

open access: yes, 1990
The α- and β-subunits of C-phycocyanin from Mastigocladus laminosus were prepared according to revised procedures. Both subunits are isolated as dimers, which can be dissociated into monomers with detergent mixtures.

Resonance polarization and phase-mismatched CARS of pheophytin b excited in the Qy band [PDF]

open access: yes, 1993
Resonance polarization and phase-mismatched coherent anti-Stokes Raman scattering (CARS) measurements were performed on pheophytin b dissolved in acetone excited in the Qy absorption band, where strong broad fluorescence makes spontaneous Raman ...

Study on the Fluorescence Spectra Characteristics of Vinegar-Water Solutions

open access: yesJournal of Spectroscopy, 2016
Fluorescence spectra and polarization spectra of vinegar-water solutions with different concentration of CH3COOH have been studied. The characteristics and mechanism of fluorescence spectra are discussed, and polarization degree is calculated.

Probing the Protein-Protein Interaction Between the ATRXADD Domain and the Histone H3 Tail

open access: yesMolecules, 2020
While loss-of-function mutations in the ATRX gene have been implicated as a driving force for a variety of pediatric brain tumors, as well as pancreatic neuroendocrine tumors, the role of ATRX in gene regulation and oncogenic development is not well ...

Fluorescence Anisotropy as a Temperature-Sensing Molecular Probe Using Fluorescein

open access: yesMicromachines, 2021
Fluorescence anisotropy, a technique to study the folding state of proteins or affinity of ligands, is used in this present work as a temperature sensor, to measure the microfluidic temperature field, by adding fluorophore in the liquid.

Testing Relativity at High Energies Using Spaceborne Detectors [PDF]

open access: yes, 2006
(ABRIDGED) The Gamma-ray Large Area Space Telescope (GLAST) will measure the spectra of distant extragalactic sources of high energy gamma-rays. GLAST can look for energy dependent propagation effects from such sources as a signal of Lorentz invariance ...
