We run LockSeq, an off‑target confirmation service for teams developing cell and gene therapies. 2020 Founded in Stockholm Padlock probes Chemistry from Prof. Mats Nilsson's lab Solna Our lab, on the Karolinska campus 15 business days From DNA receipt to report Why we exist ## Off‑target confirmation shouldn't be what holds a program back Gene-editing programs nominate dozens, sometimes hundreds, of candidate off‑target sites. Every one of them has to be sequenced deeply enough to tell a real edit from noise, and the data has to hold up in a regulatory filing. That step gets harder as panels grow, and it usually lands late. LockSeq comes out of padlock-probe research in Prof. Mats Nilsson's lab at Stockholm University and SciLifeLab, where Countagen's founders worked. We run every project ourselves, in our own lab in Solna, Stockholm, from panel design to the final report.
