A supramolecular sensor array for selective immunoglobulin deficiency analysis

Chem Commun (Camb). 2019 Sep 24;55(77):11563-11566. doi: 10.1039/c9cc06064b.

Abstract

A host-guest based fluorescence sensor array can sense small differences in protein structure. The combination of three cavitand hosts and two fluorophores to form a 4-component array is sufficient to fully discriminate five structurally similar Ig protein isotypes. The array can be applied to recognize Ig deficiencies in serum, when combined with a Protein L-based extraction process, allowing analysis of immunodeficiency in a simpler, lower cost manner than tests that require multiple specific antibodies.
