We have employed equilibrium dialysis to help study the mechanism by which the unliganded Escherichia coli trp aporepressor is activated by L-tryptophan to the liganded trp repressor. By measuring the relative affinity of L-tryptophan and various tryptophan analogues for the
Matrix-assisted laser desorption/ionisation mass spectrometry imaging (MALDI-MSI) is presently used in physiological evaluations for visualisation of targets in organs. In the present study, MALDI-MSI was used as a visualisation technique to investigate the intestinal absorption of polyphenols. Nifedipine/phytic acid-aided MALDI-MSI
In this work we characterize the interaction of cranberry (Vaccinium macrocarpon) proanthocyanidins (PAC) with bovine serum albumin (BSA) and hen egg-white lysozyme (HEL) and determine the effects of these complexes on macrophage activation and antigen presentation. We isolated PAC from

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) with nonpolar matrices has been investigated for its applicability to the characterization of atmospheric resid crude oil fractions. The data obtained by use of nonpolar matrices was compared with that from polar matrices
An approach to the optimization of product yield in an inducible inclusion body-producing system is presented. Following induction by indoleacrylic acid (IAA) of a trpLE-HIVgp41 fusion protein, we found a large increase in culture turbidity and single-cell dry weight. After
