I picked a primer sequence ,designed by the author, for my PCR from a published paper. The issue is: UCSC Insilico Pcr is not browsing that sequence, although a detailed study is done on these primers for PIK3R1 gene.
Looks like this is the human gene, is that correct? Were they testing genomic DNA or mRNA in the original paper? It may be that these are mRNA detection primers and they span an intron.
