Figure 1: Comparison of DNA concentration obtained from: (A) blood directly deposited on the cotton swabs; (B) blood deposited, dried and collected from a smooth surface (microscope slide); (C) blood deposited, dried and collected from an absorbent surface (white cotton). Values of zero indicate samples that were not quantified successfully and the shaded areas represent the expected DNA concentration [12].
