Modification by group: Others
Position of modification: 3´, 5´
Adding cholesterol increases oligonucleotide lipophility. Furthermore, cholesterol improves the permeability of oligonucleotide chains through cellular membranes in antisense oligonucleotides (phosphorothioates or other derivatives). Cholesterol may be attached either to the 5′ end or the 3′ end of the oligonucleotide.

General Terms and Conditions
Dual-labeled hydrolysis probes The technology of dual-labeled hydrolysis probes (also called TaqMan® real-time PCR probes) exploits the 5 ́-3 ́ exonuclease activity of Taq DNA polymerase to cleave the probe. TaqMan real-time PCR probes are labeled with a fluorescent dye (reporter) at the 5´ end and with a quencher at the 3´ end.
Why choose alternative dyes instead of "genuine" dyes? First, they are cheaper, and second, they can give the same results. Another reason is that the number of suppliers who can provide modified oligonucleotides is restricted - only a patent or a licence owner is usually allowed to produce them.
