X-Chem has an unrivaled track record of excellence, with nearly 100 licensed programs in DNA-encoded library (DEL)-driven discovery. Tapping into our deep well of experience, we developed ReadiBLOX — building blocks specifically designed for DEL synthesis. Our expansive catalog of ReadiBLOX encompasses a wide array of shapes, functional groups and synthetic strategies, and we regularly add to the ReadiBLOX list with our latest DEL synthesis innovations.
