Fig 3. High throughput screening yielded putative muco-active reagents from the compounds library.

A. The result of natural compound library screening. Data were analyzed by calculating the Z-score which indicates how far an individual score is away from the mean of a data set. Four putative muco-active reagents which have a Z-score over 4 or below -4 were selected for further analysis. B. The screening results of a random chemical library from NCBI. The random chemical library did not yield any muco-active reagents.
