One output of PCR primer design workflow. Screenshot of partial graphical output of PCR primer design workflow as displayed in web browser. The output is truncated for representation clarity. This figure displays the first two primer sets generated for the region chr16:23,597,600-23,597,933 of the human genome (assembly hg18). The primers and PCR product are illustrated in text followed by graphical representation of PCR region derived from UCSC genome browser. Tracks displayed from browser may be changed by adjusting workflow.
