ReadiBLOCKs Help Build the Best In-House DNA-Encoded Libraries (DEL)

With nearly 100 programs licensed, X-Chem has an unrivaled track record of delivering DNA-encoded library (DEL) – driven discovery. We tap into that experience to design ReadiBLOCKs — building blocks specifically designed to enable DEL synthesis. Our growing collection of ReadiBLOCKs encompass a wide variety of shapes, functional groups and synthetic strategies. We regularly add to the ReadiBLOCK list with our latest innovations in DEL synthesis.

We currently offer 708 DEL building blocks ready to attach to DNA (475 compounds on stock and 233 compounds resynthesizeable).

These building blocks are bi- and tri-functionalized:

  • Haloacids
  • Halo amino acids
  • Nitroalkenes
  • Amino acids
  • Amino acid esters
  • Boronic acids
  • Fmoc-protected amino compounds

Compounds can be purchased in mg quantities.

Use ReadiBLOCKs to benefit from X-Chem’s years of experience in DEL design and enhance your hit identification efforts.
