Brief Description:

A trinucleotide‐based, 16mer peptide phagemid library covering >e9 clones (“ENTE‐1”) was used for two rounds of panning against individual serum from patients sensitized to soy bean. We coated 24 μg total serum protein in 2.5 mL PBS to Immuno Tubes (MaxiSorp™; Thermo Fisher Scientific, Waltham, MA, USA) for 1 hour at 4°C under constant agitation. Under these conditions, all Ig molecules should be bound on the tube surface. A negative control was incubated with PBS only. The coated tubes were washed with 2.5 mL blocking buffer once (5% [w/v] non‐fat dry milk powder in PBS) and incubated with 4 mL blocking buffer at 4°C for at least 15 minutes under constant agitation. Before adding the ENTE‐1 peptide phage display library, the tubes were washed three times with 4 mL PBS. To preferably select patient-specific antibodies, and in particular to prevent selection of peptides binding serum proteins, a competition with a mixture of ten sera from healthy donors was conducted. The ENTE‐1 library was added to each tube in 1 mL blocking buffer containing 30 μg of non‐allergic serum protein. In the first selection round, an amount of phage corresponding to 4e11 colony forming units (cfu) of ENTE‐1 library and in the second selection only e9‐e10 cfu of recovered phage were used. Tubes were incubated for 2 hour at 4°C with constant agitation, washed five times with 1 mL 0.1% (v/ v) Tween 20 in PBS in the first selection round, and with 0.5% (v/v) Tween 20 in PBS in the second selection round.
