The enzyme EndoS from Streptococcus pyogenes is an immunomodulatory molecule hydrolyzing the conserved glycans in the effector part of immunoglobulin G (IgG). EndoS is remarkably specific for IgG, and hydrolysis has profound effects on IgG effector functions. EndoS pretreatment of

Changes in glycosylation have long been associated with disease. While there are many methods to detect changes in glycosylation, plant derived lectins are often used to determine changes on specific proteins or molecules of interest. One change in glycosylation that

Glycation of immunoglobulin G (IgG) can result from incubation with a reducing sugar in vitro or during circulation in vivo. Upon injection of a recombinantly produced human therapeutic IgG into humans, changes in the glycation levels could be observed as

A new method for simultaneously screening allelic variants and certain Fc modifications on endogenous human IgG1 and IgG2 directly from blood samples is described. The IdeS endoproteinase was used to cleave IgG in serum to generate Fc, which, after denaturation

An efficient method for synthesizing homogenous glycoproteins is essential for elucidating the structural and functional roles of glycans of glycoproteins. We have focused on the transglycosylation activity of endo-ß-N-acetylglucosaminidase from Mucor hiemalis (Endo-M) as a tool for glycoconjugate syntheses, since
