Dear Janine,

Thank you for your question. Labeled primers are typically used versus labeled dNTPs to allow for control over the number of fluorophores that are associated with each fragment. I am unaware of a protocol that uses labeled dNTPs.

If you decide to use labeled primers, TriLink offers a range of IRDyes for oligonucleotide labeling through OligoBuilder®. I’m sorry I could be of more help and good luck with your research.

Best regards,
