Figure 2.

Cell viability of OMM-1 cells challenged with 1 mM H₂O₂ after incubation with fucoidan from (a) Saccharina latissima (SL), (b) Laminaria digitata (LD), (c) Fucus serratus (FS), (d) Fucus vesiculosus (FV), (e) Fucus distichus subsp. evanescens (FE). Cell viability was measured by MTS assay and is depicted as mean and standard deviation, with the control set as 100%. All fucoidans tested displayed protective effects, with the efficacy of LD > FV > SL > FE > FS. Significance was evaluated with Friedman’s ANOVA and subsequent Student’s t-test, + p < 0.05, ++ p < 0.01, +++ p < 0.001, all versus 1 mM H₂O₂ (n = 8).
