Fig. 3. SPR sensograms (responses in RU) for binding of IgG and IgY antibodies.

Fig. 3

A: Bd-cys-S-PEG3400-biotin capture agent. Here and in Panel B, arrows indicate the times of introduction of (1) anti-GABAA-α1 rabbit IgG, (2) rat IgG2a, (3) anti-GABAA-ρ1 guinea pig IgG, (4) chicken IgY, and (5) anti-insulin chicken IgY. B: Insulin-biotin capture agent. In both A and B, sensogram electronic spikes of ≤ 4 s duration have been removed. Surface-bound Bd-cys-S-PEG3400-biotin thus specifically binds anti-GABAA-α1 IgG and anti-GABAA-ρ1 IgG.
