  • Galactose-Alpha-1,3-Galactose-Macromolecule Conjugates And Methods Employing Same
    Publication number: 20120219975
    Abstract: Methods and reagents are disclosed for conducting assays for IgE. Embodiments of the present reagents comprise a conjugate of a macromolecule and a compound comprising a galactose-?-1,3-galactose epitope. Embodiments of the present methods are directed to determining the presence and/or amount of an IgE specific for a galactose-?-1,3-galactose epitope in a sample. A combination is provided in a medium, which comprises the sample and a reagent for determining the presence and/or amount of an IgE specific for a galactose-?-1,3-galactose epitope in a sample wherein the reagent comprises a conjugate of a macromolecule and a compound comprising a galactose-?-1,3-galactose epitope. The combination is subjected to conditions for binding of the IgE to the reagent to form a complex. The presence and/or amount of the complex are detected and the amount of the complex is related to the presence and/or amount of IgE in the sample.
