From: A reliable and effective method of DNA isolation from old human blood paper cards
Concentrations, A260/A280 and A260/A230 ratios of DNA isolated from old human blood paper cards with the four different reagents (DN131, Tris–HCl, TE, H 2 O). A. DNA concentrations (ng/μl); B. A260/A280 ratios; C. A260/A230 ratios. *, p < 0.05, compared to DN131 group. T-test was performed for DNA concentrations and A260/A230 ratios because these data are normally distributed, while A260/A280 data are not normally distributed. Wilcoxon Rank-Sum test was used to examine the A260/A280 differences between methods including DN131.
