I need a DNA oligo with a fluorescent dye attached for an fluorescence polarization assay. The linker between DNA and dye should be as rigid as possible and the dye most likely a BODIPYdye, dansyl or fluorescein dye. Attachment either internal or at the 5′ of the oligo. What solution do you have for that? – Chris Gloeckner, Illumina

A shorter linker will provide the most rigidity between an oligo and a dye. Our shortest linker is the dT-C2 amino linker. The linker arm is attached to the Thymidine base and the dye would be conjugated onto the amino group post-synthetically. Another option would be to use our C7 internal amino linker. Read More…
