Molecular Assemblies

Biotech & Life Sciences · San Diego, United States · Founded 2013

A private life sciences company developing an enzymatic DNA synthesis technology designed to power the next generation of DNA-based products MoreLess

Molecular Assemblies, Inc., a San Diego-based life sciences entity established in 2013, is commercializing a novel method for synthesizing DNA. The company was co-founded by Michael J. Kamdar and Bill Efcavitch, who bring extensive experience from the genomics and life sciences sectors to the venture. Their collective background in developing and commercializing life science tools has been instrumental in steering the company's direction.

The core of Molecular Assemblies' operations is its proprietary Fully Enzymatic Synthesis (FES™) technology, which aims to produce long, high-purity strands of DNA. This method diverges from the traditional chemical synthesis process, which has been the industry standard for over four decades but is limited in the length and purity of the DNA it can produce, typically capping out at around 300 base pairs. The FES™ platform is designed to overcome these limitations by mimicking the natural process of DNA replication, potentially enabling the creation of DNA strands that are thousands of base pairs long.

The company's business model revolves around providing this advanced DNA synthesis capability as a service and potentially through future product offerings. Its primary clientele includes organizations in industrial synthetic biology, precision medicine, and data storage. For instance, in synthetic biology, long strands of high-fidelity DNA are crucial for engineering organisms to produce new drugs, chemicals, or materials. In the field of DNA-based data storage, the ability to write long, accurate DNA sequences is fundamental to developing a high-density, long-term storage medium. By offering a more reliable, affordable, and sustainable way to manufacture synthetic DNA, Molecular Assemblies addresses a critical bottleneck in these expanding markets.
