CIC bioGUNE leads the development of ReChb, the most advanced and versatile gene editing tool to date Scientists from CIC bioGUNE have created ReChb, a CRISPR tool that allows for more flexible and precise nucleic acid editing, thanks to ancestral sequence reconstruction (ASR). This breakthrough, recently published in Nature Biotechnology, has the potential to revolutionize nucleic acid editing, enhancing applications in biomedicine, gene therapy, and molecular diagnostics.
