Oligonucleotides

Share this page

Oligonucleotides are an emerging therapeutic option to target a wide range of hard-to-treat diseases, in particular those caused by genetic mutations. They are short synthetic DNA or RNA sequences that can regulate gene expression by binding to complementary sequences of mRNA in target cells. Sub-types include antisense oligonucleotides (ASOs), aptamer RNAs, and RNA interference (RNAi) oligonucleotides. Chemical modifications of oligonucleotides and advancements in drug delivery have improved drug stability and potency, reducing the requirements for quantity of drug per dose, and total number of doses. Several oligonucleotide drugs have been licensed in the last 5 years and many others are currently in the different phases of drug development.

Altasciences has expertise in the development of highly sensitive bioanalytical assays for the quantitation of oligonucleotides in complex biological matrices such as eye, liver, or brain tissue, adapted to the different critical parameters of your preclinical and clinical studies.
