Overview
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.
The activity of this enzyme is comparable to the activity of β-1,4-Galactosyltransferase, rec.

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.

Application
Incubation of β-1,4-Galactosyltransferase and UDP-Galactose with a glycoprotein leads to increased galactosylation of the glycoprotein.
