Abstract
Purpose of review: Allergenic extracts are often standardized to control for potency, either by measuring concentrations of major allergens or "overall allergenicity" by competition for IgE in pooled sera from highly allergic subjects with a reference extract. Recent developments present an opportunity to use human mAb cloned from highly allergic subjects to define potency of allergenic extracts.
Recent findings: Two recent developments present an opportunity for revising potency measurements of allergen extracts: cloning allergen specific IgE from allergic subjects and extensive epitope mapping of major allergenic proteins. Because human IgE mAb recognize biologically relevant epitopes, they present a novel opportunity to determine the potencies of allergenic extracts and may contribute to the science base for allergen standardization.
期刊介绍：
The aim of Current Allergy and Asthma Reports is to systematically provide the views of highly selected experts on current advances in the fields of allergy and asthma and highlight the most important papers recently published. All reviews are intended to facilitate the understanding of new advances in science for better diagnosis, treatment, and prevention of allergy and asthma.
We accomplish this aim by appointing international experts in major subject areas across the discipline to review select topics emphasizing recent developments and highlighting important new papers and emerging concepts. We also provide commentaries from well-known figures in the field, and an Editorial Board of internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research. Over a one- to two-year period, readers are updated on all the major advances in allergy and asthma.
