Exactmer

Exactmer is a biotechnology company focused on the large-scale synthesis of high-purity biopolymers, including oligonucleotides and peptides. The company's core technology, Nanostar Sieving, utilizes a liquid-phase synthesis approach combined with advanced membrane separation to produce exact-length polymers. This platform is designed to overcome the scalability and purity constraints of traditional solid-phase synthesis methods used in the production of RNA-based medicines. Exactmer provides contract development and manufacturing services to pharmaceutical partners, supporting the development of antisense oligonucleotides and siRNA therapies. By enabling more efficient production of complex molecules, the company aims to reduce the cost and increase the availability of next-generation therapeutics.
