Representation of the bigenic vector and gene constructs. Scheme of the different model target protein constructs used. EMPD, TM and Cyto correspond, respectively, to the extracellular membrane proximal, transmembrane and cytoplasmic domains of membrane bound t-IgE; green box, 11 amino acid long SV5 tag; red box, 15 amino acid long biotin acceptor peptide BAP; sec, secretory signal peptide.
