Figure 1From: Fish scales and SNP chips: SNP genotyping and allele frequency estimation in individual and pooled DNA from historical samples of Atlantic salmon (Salmo salar)Temporal variation of DNA quality in archived scale samples. We show relationships between A. Total DNA concentration and Year, and B. Proportion of high molecular weight DNA (> 1000 bp) and year. Each point indicates an individual DNA extraction. Samples had been normalised to 50 ng/μl based on NanoDrop Spectrophotometer before total DNA concentration and fragment sizes were measured using an Agilent 2100 Bioanalyzer.Back to article page
