I have done DNA mutation analysis by NGS using Ion Torrent PGM sequencing instrument. I did amplification of hotspot cancer mutations by using two available panels:
1- Ion Ampliseq colon and lung cancer panel, can detect up to 22 hotspot regions of genes
2- Ion Ampliseq cancer hotspot panel v2, up to 50 genes can be studied.
If you have more questions, I'm happy to tell what I know.
