I recently started working on very old hyde tissue, extracting DNA, running a HS Bioanalyzer chip. My results showed that the samples were heavily degraded down to 30bp to 50bp fragments. When I made the libraries, theoretically I should see 130bp to 150bp fragments with the adapters attached. I did a PCR amplification to enrich the libraries. I didn't size select because there was no larger pieces than 50bp in the original bioA run.
However, when I ran the second HS bioA chip with these libraries, I got this strange ladder-like read on my samples with extremely high basepairs.
Has anyone else experienced this same strange result?
