Panel D of Fig. 2 is a replication of Panel C of the same figure. A corrected Fig. 2 containing Panel D is below:

Fig. 2 Glycome profiling of untreated and hydrothermally-pretreated Populus trichocarpa biomass. Sequential extracts were prepared from untreated (A), 11 min pretreated (B), 28 min pretreated (C), and 70 min pretreated (D) biomass. The extracted materials released from each biomass sample by various reagents (as labeled at the bottom of each map) were loaded onto the ELISA plates and were screened against an array of plant glycan-directed monoclonal antibodies. The legend panel on the right of the figure displays the nature of the polysaccharides predominantly recognized by these mAbs. Antibody binding is represented as colored heat maps, with dark blue signifying no binding, white representing intermediate binding, and bright red representing the strongest binding. The bar graphs at the top indicate the amount of material recovered at each extraction step per gram of alcohol insoluble residue (AIR).
