Table 1. Values for photocytotoxic concentration (IC₅₀, µM) of photoactivated PcGal₁₆ on human bladder cancer cell lines, HT-1376 and UM-UC-3.

	HT-1376 cell line			UM-UC-3 cell line
Hours after PDT	24	48	72	24	48	72
IC50 (µM), CI95%	-	3.3 [0.6;10.7]	2.5 [2.2;2.9]	2.1 [0.9;5.0]	2.8 [2.4; 3.2]	2.6 [2.6;2.7]

IC₅₀ is the incubation concentration that inhibits the proliferation of cultures in 50%, after cells' incubation with PcGal₁₆ and irradiation. IC₅₀ values were calculated using the MTT dose response curves (24, 48, and 72 h after PDT), obtained for cells incubated with PcGal₁₆ at various concentrations for 2 h.

CI_95%: 95% Confidence interval.
