Synvitrobio is using cell-free biotech to reduce the time needed to identify potential antibiotics. To start, ribosomes are isolated from cells, usually of Escherichia coli, and mixed into a substrate of amino acids, sugar, and adenosine triphosphate. Synvitrobio uses a robotic system to pour each batch into 384 micrometer-scale test tubes, after which up to eight strands of DNA, each with up to 10,000 nucleotides, are added to each tube to replicate. Because antibiotics first attach to dangerous molecules before destroying them, Synvitrobio also adds agents of interest to the mix. The agents are modified with an appended indicator compound that glows when a molecule attaches. Should a test tube glow, Synvirobio will turn the causative DNA sequence over to another company for further research. This method is considerably faster than relying on living organisms to grow antibiotics.
