α-2,6-Sialyltransferase, rec. EQ can be used for in vitro glycoengineering of glycoproteins, e.g. therapeutic proteins, in drug development and manufacturing.
α-2,6-Sialyltansferase, rec. EQ is a highly active recombinant human glycosyltransferase, expressed in CHO cells.
The activity of this enzyme is comparable to the activity of α-2,6-Sialyltansferase, 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 .
α-2,6-Sialyltansferase, rec. EQ fulfills those criteria and can also be provided in GMP Grade upon request. Benefits of using 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 α-2,6-Sialyltansferase and CMP-NANA with a glycoprotein leads to increased sialylation of the glycoprotein.
As α-2,6-Sialyltansferase rec. EQ adds sialic acid only to galactosylated glycostructures, a galactosylation of the glycoprotein in a previous step helps to achieve higher sialylation levels. Galactosylation can be achieved by incubation of the target protein with ß-1,4-Galactosyltransferase and UDP-Galactose.
