The presented data were obtained with the lipocalin allergen Mus m 1.0102 and its cysteine mutants MM-C138A, MM-C157A and MM-C138,157A, whose structural features and unfold reversibility investigations are presented in the research article entitled “The allergen Mus m 1.0102: cysteine residues and molecular allergology” . The data were obtained by means of a Dynamic Light Scattering-based thermal stability assay, a Fluorescence-based ligand-binding assay and a basophil degranulation test, and describe proteins’ fold stability, ligand binding ability and allergenic potential, respectively. Analysis of the collected data produced the temperatures corresponding to the onset of the protein unfolding, the dissociation constants for N-Phenyl-1-naphthylamine ligand and the profiles of β-hexosaminidase release from RBL SX-38 cells, sensitized with the serum of selected allergic patients and incubated with increasing antigens concentrations. These data allow for comparison of the lipocalin allergen Mus m 1.0102 with its conserved cysteines mutants and, with regard to their potential application in allergy diagnostics and immunotherapy, they contribute to the process of recombinant allergen characterization and standardization.
