Figures in parentheses represent the mean ± SE expressed as a percentage of the mean. Note, n represents all of the variant curves recorded on 10 mucilage pads except for ANFs II and ANFs I, where a subset of curves was analyzed. Not all monomers and oligomers were analyzed because some had nonspecific adhesion that partially obscured the curve and a subsample of the ANFs I and III were analyzed.

As calculated from 536 saw-tooth curves recorded from 10 T. undulatum mucilage pads.
