CYGB and melanoma: Comparison of absolute CYGB expression values (i.e. Ct values) between the two melanoma cell lines Malme-3M and A375 (Fig. 4), indicated that Malme-3M cells contain substantially higher endogenous CYGB expression than A375, with an average expression value for Malme-3M (under normoxic conditions) more than 800 times higher as compared to A375.
