Figure 3From: Comparison of growth factor signalling pathway utilisation in cultured normal melanocytes and melanoma cell lines Phosphorylation of PKB on Ser473 and Thr308 in normal melanocytes and NZM cell lines. Western blots representative of three independent experiments. Western blots are separated into boxes representing each NZM cell line for clarity. Cells were grown in the absence of FBS for 16 hours (SS) or in the presence of FBS (Ser).Back to article page
