Abstract

We have examined conditions which will improve the solid phase in ELISAs for HBsAg and ferritin in human serum. Sheep and rabbit antibodies were used. It was found that pre-exposure of antibody to low pH, 3 M urea and temperatures as high as 82 degrees C will enhance ELISA colour in these assays. Further experiments indicate that these conditions perturb the structure of the antibody molecules and results in the exposure of new hydrophobic regions. It is speculated that these more hydrophobic molecules can bind to regions on the plastic surface normally not coated by non-perturbed molecules.

Sample preparation for peptide mapping--A pharmaceutical quality-control perspective.

In quality control of therapeutic proteins peptide mapping is used for confirmation of primary structure and detection of posttranslational modifications. The demands put on the experimental procedure are therefore different than in the case of determination of an unknown protein structure. It is here recognized that a peptide-mapping method for quality control of proteins should be inert (not induce or revert modifications), general, robust, and allow a high sample throughput. The steps prior to the separation of the generated peptides are identified as crucial for meeting these demands. This includes denaturation, reduction, alkylation, buffer exchange, solubilization, and digestion. A critical review of the literature regarding these steps is presented. Relevant options in all steps are experimentally evaluated. Novel approaches are developed for many of the steps. The result is a sample preparation procedure that essentially meets the stated demands.

Regiochemistry of nucleophilic attack by the guanine 2-amino group at the ring positions of nitrenium ions derived from carcinogenic polycyclic arylamines and nitroarenes: molecular orbital calculations and simple models.

Semiempirical AM1 molecular orbital calculations are used to compute the energetics of addition of the guanine 2-amino group to alternative ring positions of aryl nitrenium ions with the general structure ArNH+, where Ar is the phenyl and various positional isomers of the naphthyl, pyrenyl, and benzo[a]pyrenyl groups. The syn or anti orientation of the NH+ group, and factors akin to classical localization energies, are identified as key components of the differential energetics of addition to alternative ring sites. The regiochemistry predicted by the AM1 method can be qualitatively reproduced using simple HMO calculations that require trivial computational effort and, almost as well, using PMO theory that does not require the use of a computer at all. In the latter approach, the most reactive ring positions are predicted to be those where the nonbonding orbital coefficients, a0r, in the analogous odd alternant hydrocarbons are largest. These results are discussed in relation to the available experimental data for the formation of deoxyguanosin-2-yl adducts when DNA is exposed to presumed nitrenium ion precursors.

Oxidation of the skeletal muscle Ca2+ release channel alters calmodulin binding.

This study presents evidence for a close relationship between the oxidation state of the skeletal muscle Ca2+ release channel (RyR1) and its ability to bind calmodulin (CaM). CaM enhances the activity of RyR1 in low Ca2+ and inhibits its activity in high Ca2+. Oxidation, which activates the channel, blocks the binding of 125I-labeled CaM at both micromolar and nanomolar Ca2+ concentrations. Conversely, bound CaM slows oxidation-induced cross-linking between subunits of the RyR1 tetramer. Alkylation of hyperreactive sulfhydryls (<3% of the total sulfhydryls) on RyR1 with N-ethylmaleimide completely blocks oxidant-induced intersubunit cross-linking and inhibits Ca2+-free 125I-CaM but not Ca2+/125I-CaM binding. These studies suggest that 1) the sites on RyR1 for binding apocalmodulin have features distinct from those of the Ca2+/CaM site, 2) oxidation may alter the activity of RyR1 in part by altering its interaction with CaM, and 3) CaM may protect RyR1 from oxidative modifications during periods of oxidative stress.
