Oligonucleotides are short DNA or RNA molecules, oligomers, that have a wide range of applications in genetic testing, research, and forensics.Commonly made in the laboratory by solid-phase chemical synthesis, [1] these small fragments of nucleic acids can be manufactured as single-stranded molecules with any user-specified sequence, and so are vital for artificial gene synthesis, polymerase ...
Oligonucleotide synthesis is the chemical synthesis of relatively short fragments of nucleic acids with defined chemical structure ().The technique is extremely useful in current laboratory practice because it provides a rapid and inexpensive access to custom-made oligonucleotides of the desired sequence.
The use of synthetic oligonucleotides as specific probes for genetic sequence variations was pioneered by R. Bruce Wallace, working at the City of Hope National Medical Center in Duarte, California. In 1979 Wallace and his coworkers reported the use of ASO probes to detect variations in a single-stranded bacterial virus, [ 4 ] and later applied ...
Anti-miRNA oligonucleotides (also known as AMOs) have many uses in cellular mechanics. These synthetically designed molecules are used to neutralize microRNA ( miRNA ) function in cells for desired responses. miRNA are complementary sequences (≈22 bp) to mRNA that are involved in the cleavage of RNA or the suppression of the translation . [ 1 ]
Antisense therapy is a form of treatment that uses antisense oligonucleotides (ASOs) to target messenger RNA (mRNA). ASOs are capable of altering mRNA expression through a variety of mechanisms, including ribonuclease H mediated decay of the pre-mRNA, direct steric blockage, and exon content modulation through splicing site binding on pre-mRNA.

Combination of exceptional targeting capabilities of monoclonal antibodies with numerous functional modalities of oligonucleotides has been fruitful for a variety of applications with AOC including imaging, detection and targeted therapeutics. [1] [2] [3] Cell uptake/internalisation still represents the biggest hurdle towards successful ON ...
Antagomirs, also known as anti-miRs, are a class of chemically engineered oligonucleotides designed to silence endogenous microRNAs (also known as miRNAs or miRs). [1] [2] [3] Antagomirs are a kind of antisense oligonucleotide, as their sequence is complementary to their specific miRNA target. Their structure has modifications so as to make ...
