A New Standard in Lys-C Digestion: Introducing LysCERATOR™
Efficient Lys-C digestion is critical for reliable protein identification in modern proteomics workflows. Missed cleavages, incomplete protein digestion, and challenging sample types can quickly reduce confidence in downstream LC–MS analysis. To address these challenges, Genovis has launched LysCERATOR™, a new Lys-C enzyme for efficient, lysine-specific protein digestion — even under demanding conditions.

Tackling Rheumatoid Factor Interference in ADA Assays using IgMBRAZOR™
Researchers at Roche have recently described an elegant solution to address the persistent problem of rheumatoid interference (RF) in anti-drug antibody (ADA) immunoassays. IgMBRAZOR is a unique IgM-specific protease that digests human IgM at one specific site below the CH2 domain in the heavy chain, generating homogeneous F(ab’)2 and Fc fragments. By introducing IgMBRAZOR pretreatment into their experimental setup, the scientists looked to digest IgM antibodies, including those responsible for RF interference, and effectively remove them from serum samples before ADA testing.

Understanding the Functional Impact of Monoclonal Antibody Asymmetrical Fc N-Glycan Pairs using SmartEnzymes™
Scientists at Boehringer Ingelheim and collaborators have developed a novel method to generate antibodies with defined asymmetrical Fc glycoforms and evaluate their Fc receptor (FcγRs) binding properties. Combining enzymatic digestion and redox-mediated Fc recombination, Fc fragments with specific glycan pairings could be generated and their Fc receptor binding analyzed by surface plasmon resonance (SPR) spectroscopy.
