GlyTech, Inc. is focused on the application of glycan production and chemical glycosylation technologies to the development of innovative and improved medicines such as biopharmaceuticals and oligonucleotide therapeutics.

Our platform glycan and glycosylation modification technologies can:

  • Improve the efficacy of a drug candidate
  • Ensure a uniform glycosylated structure
  • Reduce the cost of a glycosylated drug while increasing its quality

Biopharmaceuticals and oligonucleotide therapeutics have become indispensable in modern medicine as therapeutics for many chronic and acute diseases that require highly specific treatments. By aiding in the development and improvement of such medicines, we seek to improve the lives of individual patients and benefit society as a whole.

Our Approach

  • From single drug-glycan conjugates to libraries, we offer chemical glycosylation of target compounds with high purity human-type glycans to enhance their drug properties.
  • We work with research and development partners to screen for optimized glycosylation patterns and develop new drug candidates.
  • We supply the biopharmaceutical industry and life science community with highly pure, homogenous human-type N-glycans from research to production scale.
