doi: 10.1038/nprot.2010.36

Figure Lengend Snippet: Using protein domain microarrays to identify and quantify domain–peptide binding interactions. (a) Fluorescent images of eight identical SH2/PTB domain microarrays in separate wells of a 96-well microtiter plate. The fluorescence arises from a trace amount of Cy5-labeled BSA that was added to each protein before arraying. (b) Fluorescent images of SH2/PTB microarrays, probed with eight concentrations of a 5(6)-TAMRA-labeled phosphopeptide derived from ErbB2 pY1139 (5(6)-TAMRA-PLTCSPQPEpYVNQPDVR). (c) Plots showing fluorescence as a function of peptide concentration for 28 high-affinity interactions. The data were fit to equation (1) to determine the KD. (d) PDZ domain microarrays probed with fluorescently labeled peptides. Each PDZ domain was spotted in quadruplicate in wells of 96-well microtiter plates (requiring four wells to include all domains). The Cy5 (red) images are used to identify PDZ domain spots. The green images depict arrays probed with fluorescently labeled peptides. (left, 5(6)-TAMRA-NNGSNAKAVETDV, a promiscuous peptide representing the C terminus of Kv1.4 and right, 5(6)-TAMRANNGQSPANIYYKV, a more selective peptide from Ephrin B1/2).(e) FP titration curves obtained for the array positives identified in (d).
