Anisotropy resolved multidimensional emission spectroscopy (ARMES): A new tool for protein analysis
(Elsevier, 2015-07-30)Structural analysis of proteins using the emission of intrinsic fluorophores is complicated by spectral overlap. Anisotropy resolved multidimensional emission spectroscopy (ARMES) overcame the overlap problem by the use ... -
Characterization of Lysozyme PEGylation products using polarized Excitation Emission Matrix (pEEM) spectroscopy
(Wiley, 2020-07-07)The growing use of therapeutic proteins requires accurate measurement techniques for measuring biophysical and structural changes during manufacturing. This is particularly true for PEGylation of proteins, because ... -
Conformations of myoglobin-derived peptides at the air-water interface
(NUI Galway, 2016-12-12)Simulation files, analysis scripts, and output data to accompany article: Cheung, David L. (2016). Conformations of Myoglobin-Derived Peptides at the Air–Water Interface. Langmuir, 32(18), 4405-4414. doi: 10.1021/acs.la ... -
Conformations of myoglobin-derived peptides at the air-water interface
(American Chemical Society, 2016-04-14)The conformational change exhibited by proteins at liquid interfaces, such as the air-water and oil-water interfaces, has long been of interest, both for understanding protein structure outside of native environments and ... -
Decorated macrocycles via ring-closing double-reductive amination. Identification of an apoptosis inducer of leukemic cells that at least partially antagonizes a 5-HT2 receptor
(American Chemical Society, 2015-03-16)A build-couple-pair strategy, including double-reductive amination macrocyclization, has been used to generate decorated macrocycles (eannaphanes) with an embedded triazole and monosaccharide. Biological screening led to ... -
A fluorescence anisotropy method for measuring protein concentration in complex cell culture media
(Elsevier, 2014-03-12)The rapid, quantitative analysis of the complex cell culture media used in biopharmaceutical manufacturing is of critical importance. Requirements for cell culture media composition profiling, or changes in specific analyte ... -
Fluorescence study of bovine serum albumin and Ti and Sn Oxide nanoparticles interactions.
(The Optical Society, 2007)Nanochemistry offers stimulating opportunities for a wide variety of applications in the biosciences. Understanding of the interaction of nanoparticles with biomolecules such as proteins is very important as it can help ... -
Investigating native state fluorescence emission of Immunoglobulin G using polarized Excitation Emission Matrix (pEEM) spectroscopy and PARAFAC
(Elsevier, 2018-12-20)Intrinsic fluorescence spectroscopy (IFS) measurements for protein structural analysis can be enhanced by the use of anisotropy resolved multidimensional emission spectroscopy (ARMES). ARMES attempts to overcome the ... -
Investigating tryptophan quenching of fluorescein fluorescence under protolytic equilibrium
(2009)Fluorescein is one of most used fluorescent labels for characterizing biological systems, such as proteins, and is used in fluorescence microscopy. However, if fluorescein is to be used for quantitative measurements involving ... -
Modelling Förster resonance energy transfer (FRET) using anisotropy resolved multi-dimensional emission spectroscopy (ARMES)
(Elsevier, 2020-11-16)Background Förster Resonance Energy Transfer (FRET) is widely used to study the structure and dynamics of biomolecular systems and also causes the non-linear fluorescence response observed in multi-fluorophore proteins. ... -
Monitoring local unfolding of bovine serum albumin during denaturation using steady-state and time-resolved fluorescence spectroscopy
(Springer, 2010-03)In a previous report (J. Fluoresc. 16, 153, 2006) we studied the chaotropiclly induced denaturation of Bovine Serum Albumin (BSA) using the fluorescence decay kinetics at different stages in the denaturation of BSA by ... -
Multi-attribute quality screening of immunoglobulin G using polarized Excitation Emission Matrix spectroscopy
(Elsevier, 2019-12-10)Immunoglobulin G (IgG) is often used as a starting material for the production of functionalised antibodies, like Antibody Drug Conjugates (ADCs), PEGlyated-conjugates, or radioimmunoconjugates. The gross structural quality ... -
Quantitative analysis of weakly bound insulin oligomers in solution using polarized multidimensional fluorescence spectroscopy
(Elsevier, 2020-09-08)Being able to measure the size and distribution of oligomers in solution is a critical issue in the manufacture and stability of insulin and other protein formulations. Measuring oligomers reliably can however be complicated, ...
