Electrochemical detection of SEB binding on an array with Ppy deposited using constant current.

<p>Polypyrrole was deposited using currents from 10 to 260 nA for 0.1, 0.5, 1.0, or 2.0 s. Different concentrations (0, 0.1, 1.0 or 10.0 pg/ml) of SEB were incubated in individual chambers of a four-chamber hyb cap, and binding was detected using biotinylated rabbit anti-SEB with HRP-SA.
