Figure 7From: Ageing of enteric neurons: oxidative stress, neurotrophic factors and antioxidant enzymesExamples of Western blots of lysates from sister cultures grown in the presence of NT-3 or GDNF for 12 hours (a) or 36 hours (b) prior to protein extraction, using antibodies directed against catalase (middle row)or superoxide dismutase Cu/Zn (bottom row). 5 μg of protein extracts was loaded on to each gel. To ensure equal protein content on each lane after electro blotting membranes were incubated with Ponceau red (top row), and protein amounts were estimated using densitometry.Back to article page
