10-P177_WB
Presence of sIgE antibodies specific to recombinant allergens Bet v 1, Bet v 2, Bet v 4, Bet v 6, and Bet v 7 was analysed in plasma of a patient with confirmed presence (routine clinical test) of specific IgE antibodies to birch pollen allergen extract.

Western blotting analysis was performed on recombinant allergens rBet v 1, rBet v 2, rBet v 4, rBet v 6, and rBet v 7 mixed and heated (100°C, 5 min) with reducing SDS loading buffer. Samples were resolved using 12% SDS-PAGE gel. Nitrocellulose membrane blot was incubated with plasma of an allergic patient (1:10). Captured 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 Bet v 2, Bet v 6, Bet v 7.
10-P177_čistota
Recombinant allergen rBet v 2 purity verification. 5 µg of rBet v 2 with > 95 % purity checked by Coomassie Brilliant Blue stained SDS-PAGE.
10-P177_ELISA
ELISA (enzyme-linked immunosorbent assay) test was designed to prove the bond between the coated target recombinant allergen rBet v 2 and allergen-specific human plasma IgG4 antibodies of Betula verrucosa 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 rBet v 2.
10-P177_FC_Dot-plot
Flow cytometry dot-plot staining pattern of rBet v 2 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.
