Figure 3From: Recombinant phospholipase A1 (Ves v 1) from yellow jacket venom for improved diagnosis of hymenoptera venom hypersensitivityBasophil activation. Basophils from two YJV-sensitised patients (A and B) were stimulated with 0.1-2000 ng/ml of rVes v 1 (open squares) and rVes v 5 (filled circles). Activation was determined by CD63 upregulation in FACS. Control stimulation was performed with 50 ng/ml YJV (diamonds).Back to article page
