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

trp repressor of Escherichia coli controls transcription initiation in operons involved in tryptophan biosynthesis by binding to operator sequences within the regulated promoters. Naturally occurring operators are homologous over an 18-base pair region and display dyad symmetry. We have examined

Two of the main problems associated with matrix-assisted laser desorption-ionization time-of-flight (MALDI-TOF) analysis of polymers are mass discrimination and poor reproducibility. This paper shows that the use of binary solvent systems is one of the causes of these problems. It
