I'm trying to check the primers and probe design from a paper. I'm using primer-BLAST to do so for the primers, but I'm not sure how to check the probe sequences.
If you want to check the probe sequence position within targeted genome sequences you can just blast it in blastn: https://blast.ncbi.nlm.nih.gov/Blast.cgi?PROGRAM=blastn&PAGE_TYPE=BlastSearch&LINK_LOC=blasthome
Alternatively, you can use BioEdit and the search option to check the probe sequence positions.
If you are looking for online tools to design TaqMan PCR sets, for example, you can check:
