OligonucleotidesOligonucleotides are small nucleic acid polymers, usually less than 20 bases in length. Oligonucleotides can be made via enzymatic cleavage or more commonly by chemical synthesis with polymerases. Their use includes FISH, southern blots, microarrays and as primers in PCR. High fidelity synthesis kits and detection systems are available for easy production and detection, respectively.Conjugation
