Sensing Proteins with Luminescent Silica Nanoparticles

Langmuir, 2009
Nanometer sized silica nanoparticles (SiO2-NP) were prepared in water and loaded with two organic compounds, namely perylene and 1,6-diphenyl-1,3,5-hexatriene, which have well-defined and known fluorescence properties. The size of void and dye-doped SiO2-NP were determined by both transmission electron microscopy and atomic force microscopy, which ...

The chromophore of pholasin: A highly luminescent protein

Journal of Bioluminescence and Chemiluminescence, 1990
AbstractPholasin is the photoprotein extracted from the marine bivalve Pholas dactylus. It undergoes an oxidative chemiluminescent reaction to oxypholasin with superoxide anion, hypochlorite, peroxidases and other oxidants. Since the observed absorbance and chemiluminescent emission spectra of pholasin solutions cannot be brought about solely by the ...

Advances in the study of luminescence probes for proteins

Journal of Chromatography B, 2004
Spectral probes (or labels) have been widely used for the investigation and determination of proteins and have made considerable progress. Traditional luminescence probes include fluorescent derivatizing reagents, fluorescent probes and chemiluminescence probes which continue to develop.

Confinement-Enhanced Luminescence in Protein–Gold Nanoclusters

The Journal of Physical Chemistry Letters, 2020
Confinement has profound effects on protein functions. Nanoscale probes for confinement or excluded volume interactions could help us understand how these interactions influence protein functions. This work reports on the increased luminescence of BSA-gold nanoclusters when confined.

Thermally Stimulated Luminescence in Powdered Soy Proteins

Journal of Food Science, 2013
Abstract Heating powder isolated soy proteins (ISPs) in a N 2 environment produced thermally stimulated luminescence (TSL), in 2 major temperature regions, 50 to 250°C (region R1) and 250 to 350°C (region R2).

Engineering of Highly Luminescent Lanthanide Tags Suitable for Protein Labeling and Time-Resolved Luminescence Imaging

Journal of the American Chemical Society, 2004
The synthesis of a new ligand LH(4) based on a glutamic acid skeleton bis-functionalized on its nitrogen atom by 6-methylene-6'-carboxy-2,2'-bipyridine chromophoric units is described. UV-vis spectrophotometric titrations revealed the formation of 1:1 M:L complexes with lanthanide(III) cations, and complexation of LH(4) with equimolar amounts of ...

Structure of Lumazine Protein, an Optical Transponder of Luminescent Bacteria

Journal of Molecular Biology, 2008
The intensely fluorescent lumazine protein is believed to be involved in the bioluminescence of certain marine bacteria. The sequence of the catalytically inactive protein resembles that of the enzyme riboflavin synthase. Its non-covalently bound fluorophore, 6,7-dimethyl-8-ribityllumazine, is the substrate of this enzyme and also the committed ...

Luminescence of Polypeptides and Proteins

1971
It is frequently advantageous to consider the evolution of ideas and results when surveying a particular area of reseach since the early results often contain the fundamental outlines of a problem which subsequently become obscured by the later accumulation of detailed knowledge. The history of the development of protein fluorescence followed a logical

Mitochondria and calcium homeostasis: a tale of three luminescent proteins

Luminescence, 2001
AbstractIn recent years the jellyfish Aequorea victoria has provided the scientific community with a pair of tools of exceptional usefulness: aequorin and the green fluorescent protein (GFP). Whereas the former has played a major role in the study of calcium signalling, the latter has sparked the imagination of researchers into a myriad of elegant ...

An enzyme-coupled ultrasensitive luminescence assay for protein methyltransferases

Analytical Biochemistry, 2010
Epigenetic regulation through protein posttranslational modifications is essential in development and disease. Among the key chemical modifications is protein methylation carried out by protein methyltransferases (PMTs). Quantitative and sensitive PMT activity assays can provide valuable tools to investigate PMT functions.
