Oligonucleotides

Oligonucleotides are short RNA or DNA oligomers with a wide range of applications in microarrays, gel shift assays, artificial gene synthesis, PCR, DNA sequencing, molecular cloning, forensics, and other research applications. Oligos are available in various primer lengths and may be pre-designed, customized, or randomized.
