β-1,4-Galactosyltransferase, rec. EQ can be used for in vitro glycoengineering of glycoproteins, e.g. therapeutic proteins, in drug development and manufacturing.
β-1,4-Galactosyltransferase, rec. EQ is a highly active recombinant human glycosyltransferase, expressed in CHO cells.

To use in vitro glycoengineering in drug development and manufacturing processes, enzymes should be of enhanced quality (EQ), compared to enzymes used in early R&D or analytical applications: Enzymes should be tested for host-cell impurities and relevant metal impurities and be available at least in gram amounts.
β-1,4-Galactosyltransferase, rec. EQ fulfills those criteria and can also be provided in GMP Grade upon request.
Benefits from in vitro glycoengineering to modify glycosylation of therapeutic proteins:
  • Time- and cost-saving generation of glycan variants to facilitate drug development.
  • Optimized glycosylation without compromising other CQAs or product yield.
  • Improved lot-to-lot consistency to reduce risk of product quality variation and resulting delays.
  • Generation of glycoprofiles which may not otherwise be generated.
  • Streamlined analytics in comparability studies.
Incubation of β-1,4-Galactosyltransferase and UDP-Galactose with a glycoprotein leads to increased galactosylation of the glycoprotein.
