Biodegradable Polymers Induce CD54 on THP-1 Cells in Skin Sensitization Test
RFI results for each biodegradable polymers. Only living cells were selected by using PI dye. Next, we displayed living cells as FITC histograms, and then we showed the power of the Geom mean. RFI (%) was calculated from Geom mean as described in test. (a) P1, (b) P2, (c) P3, (d) P4, (e) P5, and (f) P6, N.T.: not tested.
