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.
