STAMBP and melanoma: To evaluate the toxicity of the bromophenols in B16F10 melanoma cells, cell viability upon bromophenol treatment only (Figure 5A) and/or co-treatment with 5 μM α-MSH for 48 h (Figure 5B) was determined using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.
