In addition to the amino acid sequence, the activity of an antibody is also significantly affected by post-translational modifications (PTMs). Among the many PTMs, glycosylation modifications are one of the most important and complex modifications, accounting for more than 50%. Its glycosylation site, type, and abundance may affect the efficacy, safety, and quality stability of the antibody. Glycosylation modification is affected by many factors such as cell line, culture conditions, and purification process. Creative Biolabs offers a range of kits related to Glycan Analysis to help you better control the process of glycosylation.
