The optimal recognition of penicillin determinants, including amoxicillin (AX), by specific IgE antibodies is widely believed to require covalent binding to a carrier molecule. The nature of the carrier and its contribution to the antigenic determinant is not well known. Here we aimed to evaluate
An advanced design of a denuder impactor (DI) sampler has been developed for characterization of possible airborne isocyanate exposure in different particle size fractions. The sampler is equipped with 12 different parallel denuder tubes, 4 impaction stages with the cut-off values (d50) of: 9.5, 4,
Candidate drugs that can be metabolically transformed into reactive electrophilic products, such as epoxides, quinones, and nitroso compounds, are of special concern because subsequent covalent binding to bio-macromolecules can cause adverse drug reactions, such as allergic reactions,
Two molecules 9 and 14, representatives of two series of electrophilic lactone derivatives, have been synthesized, and labeled with carbon 13 at their reactive sites. The mechanism and the products of the reaction of these two molecules with human serum albumin (HSA) under various reaction
In order to evaluate the antigenic contribution of different regions of the penicillin molecule, monoclonal antibodies were raised against amoxicillin-protein conjugates and their specificities analysed in detail. A random sample of the clones produced was analysed by a quantitative
BACKGROUND
The cross-reactivity between penicillins and cephalosporins can be influenced by different factors, which are not all well known. The chemical structure of the side chain may contribute to the cross-reactivity.
OBJECTIVE
The study was carried out in allergic subjects who are selectively
