Figure 5From: A pool of peptides extracted from wheat bud chromatin inhibits tumor cell growth by causing defective DNA synthesis Analysis of p21 expression in Hela and U2OS cell lines. Western Blot analysis was performed in the cells treated for 24 and 96 hours with the peptide fraction. Densitometric quantification of p21 levels were obtained following normalization with tubulin. The molecular weight standards are shown on the left.Back to article page
