Figure Lengend Snippet: Reagents are loaded in a 96-well plate, and a programming script is used to control their flow into a single chamber or into four chambers containing an ElectraSense microarray. Current or voltage can be applied to single or groups of electrodes for Ppy deposition, and current can be read from a single electrode or groups of electrodes for ECD.

Figure Lengend Snippet: A ) Three concentrations (0.003, 0.01, and 0.03 pg/ml) were incubated on a microarray with either anti-SEB MAb (•-•) or casein (▪-▪) adsorbed onto Ppy that was deposited at 40 nA for 1 s. SEB binding was detected using biotinylated rabbit anti-SEB Ab and SA-HRP. Background (0 pg/ml SEB) was 1147±283. B ) Different concentrations of SEB were incubated on a microtiter plate with anti-SEB MAb adsorbed onto the surface of each well. SEB binding was detected using biotinylated rabbit anti-SEB Ab and SA-HRP. Background (0 pg/ml SEB) was OD 450–570 2.939±.026.
