UniProt ID Q9SWR4
10-P192_ELISA
ELISA (enzyme-linked immunosorbent assay) test was designed to prove the bond between the coated target recombinant allergen rCor a 1 and allergen-specific human plasma IgG4 antibodies of Corylus avellana positive donor. A measurable signal was subsequently generated by the addition of biotin labeled anti-human IgG4 (detection) antibody, Streptavidin-HRP and substrate solution (TMB). The intensity of the signal is proportional to the amount of coated rCor a 1.
10-P192_čistota
Recombinant allergen rCor a 1 purity verification. 5 µg of rCor a 1 with > 95 % purity checked by Coomassie Brilliant Blue stained SDS-PAGE.
10-P192_FC_Profil Značení
Flow cytometry dot-plot staining pattern of rCor a 1 recombinant allergen stimulated human peripheral whole blood lymphocytes and basophils of a proven allergic donor stained using anti-human CD63 (MEM-259) FITC and anti-human CD203c (NP4D6) PE antibodies of BasoFlowEx kit.
10-P192_WB
Reactivity of rCor a 1 with sIgE antibodies in plasma of a patient with confirmed presence (routine clinical test) of specific IgE antibodies to common hazel pollen.

Western blotting analysis was performed on recombinant allergen rCor a 1 mixed and heated (100°C, 5 min) with reducing SDS loading buffer. Sample was resolved using 15% SDS-PAGE gel. Nitrocellulose membrane blot was incubated with plasma of an allergic patient (1:10). Captured rCor a 1 sIgE antibodies were detected by biotinylated anti-human IgE secondary antibody (2 μg/ml) followed by IRDye 800CW Streptavidin (1:5000).
10-P192_WB2
Analysis of presence of sIgE antibodies specific to Cor a 1 (a common hazel antigen) in plasma of a patient with allergic reaction to common birch pollen (confirmed by routine clinical test).

Western blotting analysis was performed on recombinant allergen rCor a 1 mixed and heated (100°C, 5 min) with reducing SDS loading buffer. Sample was resolved using 15% SDS-PAGE gel. Nitrocellulose membrane blot was incubated with plasma of an allergic patient (1:10). Captured rCor a 1 sIgE antibodies were detected by biotinylated anti-human IgE secondary antibody (2 μg/ml) followed by IRDye 800CW Streptavidin (1:5000).

The analysed patient plasma contained sIgE antibodies specific to Cor a 1.
