We’re thrilled to share a new toolkit for mammalian synthetic biology: the COMET library of synthetic transcription factors, promoters, and accompanying models. Congratulations to Patrick, Joseph, Joe and Hailey and our key collaborator Neda Bagheri! This is true tour-de-force many years in the making, and we’re excited to share this with the community! Check out our preprint here, and follow some twitter discussion here.
