a, The fluorescence intensity of PCFPs in the green state without osmium acid treatment (shaded) and with 1% OsO4 incubation for 15 min (empty). All groups have the same concentration of purified fluorescent protein (0.125 mg/ml). Bars represent mean ± s.d., n = 3 independent experiments. b, Comparison of fluorescence retention ratio of PCFPs in the green state after OsO4 treatment. Bars represent mean ± s.d., n = 3 independent experiments.
