Figure 1From: Utility of arsenic-treated bird skins for DNA extractionOverall PCR success. PCR success (in percent) of three mt CR amplicons. For each amplicon, total success and success per period (until 1971 & after 1971) is given. Grey columns - foot pads, empty columns - skin samples. Note that pre-1971 samples consist of arsenic-treated samples, post-1971 samples were untreated.Back to article page
