The recent shocking reports about a human genome editing experiment have led to increased murmurings about the potential pitfalls of improved access to molecular technologies. Sharing speeds science. That’s been the driving concept behind Addgene since its founding. Nowhere has this proved more prescient than in the acceleration of basic research using CRISPR-Cas9 genome editing tools. It would be a tremendous loss of efficiency and funding if this rogue experiment resulted in a reduction in repository deposits and the sharing of research materials.
