Cobomarsen is a locked nucleic acid (LNA)-based antisense oligonucleotide that selectively inhibits microRNA-155 (miR-155). Supplied as a solid (white to off-white) research reagent, it is used in preclinical studies to modulate miR-155-driven signaling and investigate oncology models by affecting pathways such as JAK/STAT, MAPK/ERK, and PI3K/AKT. The sodium salt form offers improved stability; the compound is highly water soluble and requires sealed, moisture-free storage.
- Selective inhibition of miR-155 and related survival pathways
- Suitable for preclinical oncology and lymphoma research
- High aqueous solubility; may require ultrasonication
- Improved stability as the sodium salt compared with the free acid
- Store sealed and protected from moisture; long-term storage in solution at -80 °C
