Figure 1. Synthetic miR166b entry into silkworm hemolymph and fat body after silkworm ingestion as determined by droplet digital PCR.

The copy number counts of miR166b in 80 ng small RNA of silkworm hemolymph, 240 ng total RNA of fat body, and 240 ng total RNA of silk gland were investigated by droplet digital PCR before (0 h) and following ingestion of 300 pmol synthetic miR166b (0.5 h, 3 h, 6 h, and 12 h).
