The probe labels are provided in the assay documentation and also online. Simply look up the assay by typing the assay ID into the search bar on thermofisher.com. Click on the View Details button, and under the Product Details look for the Context Sequence. The assays are always in a [VIC/FAM dye] order. From the context sequence, you can see which base is first (thus labeled with VIC dye), and which is second (thus labeled with FAM dye).
