In Vitro Glycoengineering (IVGE)

Glycosylation is a common type of post-translational modification that can significantly influence protein stability, biological activity, and pharmacokinetics of the final products. Therefore, one way to manipulate glycosylation is through IVGE. 

LakePharma is teaming up with Roche CustomBiotech to offer custom IVGE service designed to improve therapeutic protein production. With a two-step reaction of galactosylation followed by sialyation, glycoforms can be enriched with known kinetics and predictable outcomes.

  1. Original sample will be aliquoted for glycan profiling and characterization assays.
  2. The sample will undergo two steps of the reaction, galactosylation, and sialylation.
  3. Protein-to-enzyme ratios are determined within the "IVGE Process Optimization" step.
  4. Samples will be polished using an appropriate purification method.
  5. Samples after reaction will undergo glycan profiling and characterization assays for comparison.
