α-2,6-Sialyltransferase, rec. can be used for in vitro glycoengineering of glycoproteins, e.g. therapeutic proteins.
α-2,6-Sialyltansferase, rec. is a highly active recombinant human glycosyltransferase, expressed in HEK-293F.
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 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.
