Honey-Induced Protein Stabilization as Studied by Fluorescein Isothiocyanate Fluorescence
Protein stabilizing potential of honey was studied on a model protein, bovine serum albumin (BSA), using extrinsic fluorescence of fluorescein isothiocyanate (FITC) as the probe. BSA was labelled with FITC using chemical coupling, and urea and thermal denaturation studies were performed on FITC-labelled BSA (FITC-BSA) both in the absence and presence of 10% and 20% (w/v) honey using FITC fluore...
متن کاملTautomerism of 4,4′-dihydroxy-1,1′-naphthaldazine studied by experimental and theoretical methods
BACKGROUND The title compound belongs to the class of bis-azomethine pigments. On the basis of comparative studies on similar structures, insight into the complex excited state dynamics of such compounds has been gained. It has been shown, for example, that only compounds that possess hydroxyl groups are fluorescent, and that the possibility for cis-trans isomerisation and/or bending motions of...
متن کاملEpidemiology of human rotavirus Types 1 and 2 as studied by enzyme-linked immunosorbent assay.
To determine the relative importance of two known serotypes of human rotavirus, we developed an enzyme-linked immunosorbent assay to differentiate serotype-specific rotavirus antigen and antibody. Using this technic, we studied the epidemiology of the two serotypes in acute gastroenteritis. Seventy-seven per cent of 414 rotavirus isolates were Type 2, and the remainder were Type 1. The serotype...
متن کاملDiffusion in Model Networks as Studied by NMR and Fluorescence Correlation Spectroscopy
We have studied the diffusion of small solvent molecules (octane) and larger hydrophobic dye probes in octane-swollen poly(dimethyl siloxane) linear-chain solutions and end-linked model networks, using pulsed-gradient nuclear magnetic resonance (NMR) and fluorescence correlation spectroscopy (FCS), respectively, focusing on diffusion in the bulk polymer up to the equilibrium degree of swelling ...
متن کاملSegmental flexibility in Escherichia coli ribosomal protein S1 as studied by fluorescence polarization.
Ribosomal protein S1 covalently reacts with approximately one equivalent of iodoacetylethylenediamine (1,5-napthol sulfonate (IAEDANS) or iodoacetylaminofluorescein (IAAF). The product AEDANS-S1 can bind to 30S ribosomal subunits lacking S1 as shown by polyacrylamide-agarose gel electrophoresis AEDANS-S1 and AAF-S1 when added back to S1-depleted 30S subunits modulate poly(U)-dependent polypheny...
