Plant cell wall directed monoclonal antibodies (mAbs) bind to xyloglucan fragments 6–18. (A) Microarray scans showing binding of selected antibodies to xyloglucan oligosaccharides. Each compound was printed in four concentrations as indicated on the right. (B) Binding of mAbs specific to galactosylated xyloglucan. The obtained fluorescence values were normalized against the highest value on the microarray and are displayed as percentages. To remove background signals, only values above 4% are displayed. The complete list of investigated xyloglucan-directed mAbs can be found in ESI Fig. 1.^†
