About Tessera’s GENE WRITER Technology

Tessera’s GENE WRITER tools are based on nature’s genome architects, Mobile Genetic Elements (MGEs)—the most abundant class of genes across the tree of life, representing approximately half of the human genome. Tessera has evaluated tens of thousands of natural and synthetic MGEs to create GENE WRITER candidates with the ability to write therapeutic messages into the human genome. Tessera’s research engine further optimizes the discovered GENE WRITER candidates for efficiency, specificity, and fidelity—essentially compressing eons of evolution into a few months.
