Western blot analysis of extracts from NIH/3T3, HeLa and COS cells, untreated or treated with TPA, using Phospho-c-Raf (Ser338) (56A6) Rabbit Monoclonal Antibody E3452-50.
Mitotic HeLa cells stained with Phospho-MEK1/2 (Ser217/221) Antibody E3452-50 (red) and counterstained with anti-tubulin (green) to detect microtubules and the mitotic spindles of dividing cells. Active MEK was highly concentrated at the spindle poles (yellow). (Provided by Dr. Harry Mellor, University of Bristol, UK.)
