Figure 5From: Long-term cultivation of colorectal carcinoma cells with anti-cancer drugs induces drug resistance and telomere elongation: an in vitrostudyThe effect of cultivation with anti-cancer drugs on the telomere length. The telomere length was measured by a TRF Southern blot analysis as described in the Materials and Methods. Peak and mean telomere restriction fragment (TRF) length was calculated by using an NIH image software.Back to article page
