Mechanistic Insights to Drive Rational Design of Masked Antibodies using FabALACTICA®
Scientists at the University of Cambridge, Astra Zeneca and collaborators undertook mechanistic studies to investigate antibody masking and better understand the parameters involved and their relative impact. FabALACTICA proved to be a valuable tool in this study, allowing the authors to generate antibody subunits. Using the Fab region, as opposed to the full-length antibody, allowed…
NEW! We’re Launching GlySERIAS Immobilized
GlySERIAS is a unique enzyme that digests flexible glycine-rich fusion protein linkers such as Gly4Ser and GlyxSery (GS), and polyglycine (G) linkers. Today, we're happy and proud to be launching this unique SmartEnzyme in a new format - GlySERIAS Immobilized - for digestion of flexible linkers in easy-to-use spin columns! The enzyme enables separation…
It’s Time for a Change!
As part of our overall strategy to become even more sustainable and caring for the environment, we are updating our product boxes (see below). When updating the boxes, we also want to make it easier for you to know what you get when you buy or search for a product from us. We are therefore…
FabULOUS™ in HIV Vaccine Research
The Fc N-glycosylation profile can be linked to non-neutralizing functions in a vaccine. In a recent study by Chen et al., FabULOUS digestion provided valuable insights in HIV vaccine research following N-glycosylation analysis of the Fc region in mouse antibodies.
Welcome to Join Our First GenovisWebinar!
We are excited to announce our series of GenovisWebinars, and we are happy to invite you to the first webinar held on November 17th! Each webinar will showcase inspirational SmartEnzymes user, and the topics discussed are influenced by how to improve analytical workflows. Please join us in sharing experiences!
Localization of O-glycan Sites in CD24Fc by OpeRATOR® Digestion and LC-MS Analysis
Scientists from Merck & Co. and Glycotope describe the localization of 12 O-glycosylation sites in the heavily O-glycosylated fusion protein CD24Fc by digestion with the O-glycoprotease OpeRATOR in combination with LC-MS analysis. Two different workflows were developed, one based on fractionation in combination with LC-MS/MS CID and one based on LC-MS/MS EThcD. OpeRATOR digestion enabled…
Antibody LC-MS Analysis Service from Genovis!
We offer fast and accurate LC-MS profiling of human IgG using unique sample preparation based on SmartEnzymes workflows. Our SmartEnzymes enable middle-level LC-MS analysis of antibodies to characterize critical quality attributes such as the glycosylation profile and mass confirmation.
FabRICATOR® in Correlative N-glycan Analysis of Cetuximab Produced in Different Expression Systems
A strategy for comparative characterization of cetuximab produced in a variety of expression cell lines is described in this paper from scientists at the National Institute for Bioprocessing Research and Training (NIBRT) in Dublin, Ireland. FabRICATOR (IdeS) is a critical tool in this study, allowing for site-specific glycan analysis to be performed following antibody digestion…
The Click Chemistry used in GlyCLICK® is Awarded the Nobel Prize!
Every autumn, the Royal Swedish Academy of Sciences announces the winners of the prestigious Nobel Prize. This year’s Chemistry Prize goes to Carolyn Bertozzi, Barry Sharpless and Morten Meldal for the development of click chemistry and bioorthogonal chemistry. Click chemistry is a fundamental part of our GlyCLICK technology. By combining Fc glycan remodeling and the…
Unravelling Structural Conformers within a Therapeutic Multispecific mAb using FabALACTICA
Scientists at the University of Strasbourg and Sanofi describe the global structural characterisation of a trispecific antibody which exhibits two distinct structural isoforms when analyzed by size-exclusion chromatography (SEC). FabALACTICA proved to be a valuable tool in this study as above hinge digestion of this trispecific antibody allowed for middle-level characterisation of the isomeric Fab…
FabRICATOR® in Middle-Up Quantitative N-Glycan Profiling of Therapeutic Monoclonal Antibodies
A middle-level approach to glycan characterisation is described in this paper by scientists at the University of Geneva and collaborators. FabRICATOR (IdeS), a critical tool in this study, is used to generate Fd’, LC and the glycan-containing Fc subunits, which can be chromatographically separated using HILIC and characterised using mass spectrometry.
