GMP Protein Manufacturing Services

Put our GMP expertise to work for you.

column chromatographyOur expertise with protein-based therapies extends from the discovery of IL-2 and covers over 30 years of GMP manufacturing support for biopharmaceutical companies and US government clients.  ABL supports industry, academic and government clients developing

  • Monoclonal antibodies
  • Glycoproteins
  • Virus-like particles (VLPs)
  • Fusion proteins
  • Immunotherapeutics
  • Critical reagents for diagnostic assays
