The leading provider of critical life science research products and services, Amerigo Scientific, introduced its mass spectrometry grade enzymes engineered to eliminate background artifacts, boost cleavage specificity, and deliver reproducible LC-MS/MS results across all protein analysis workflows.

Mass spectrometry grade enzymes represent ultra-purified, chemically modified proteases refined specifically for proteomic digestion and sample preprocessing. Unlike standard lab proteases, these reagents undergo rigorous purification and reductive methylation treatments to suppress non-specific autolysis and off-target proteolytic activity, which prevents unwanted noise peaks and ambiguous signals during mass spectrum acquisition. Amerigo Scientific’s specialized proteolytic enzymes are designed with distinct cleavage profiles to resolve complex protein samples and expand measurable protein sequence coverage.

The proteolytic enzyme products span traditional animal-derived and fully recombinant variants to fit diverse research and industrial needs. Flagship offerings include standard trypsin, ultra-fast recombinant Trypsin 3.0, mirror proteases rTrypsin-N and rLys-N, combined rTrypsin/rLys-C complex, rLys-C, rGlu-C, rArg-C, chymotrypsin and rAsp-N. Each protease targets defined amino acid termini—either C-terminal or N-terminal cleavage at arginine, lysine, glutamate, aspartate or aromatic residues—enabling researchers to select single enzymes or sequential digestion combinations to resolve digestion gaps and precisely map post-translational modifications (PTMs) such as phosphorylation, methylation, and glycosylation. These specific proteolytic enzymes serve as foundational tools for protein identification, quantitative proteomics, single-cell research, neurodegenerative disease biomarker study, and biotherapeutic peptide mapping.

Complementing the proteomics toolkits, Amerigo Scientific features dedicated glycoproteomics and glycan analysis enzymes tailored for targeted characterization of N-linked and O-linked protein glycosylation, a critical PTM category for antibody drug development and glycoproteomic research. This subset includes O-Glycoprotease for O-glycosylation site profiling, rEndo S2 for IgG Fc glycan cleavage and rPNGase F for universal N-glycan removal. The glycoproteomics and glycan analysis enzymes avoid structural bias toward sialic acid or core fucose residues, supporting intact glycoprotein mass testing, glycan site localization and high-throughput glycan profiling for biopharma quality control pipelines.

Beyond protein and glycan processing, Amerigo Scientific expands the mass spectrometry grade enzymes portfolio with auxiliary reagents to address full pre-analytical workflow challenges. Its antibody engineering and conjugation enzymes deliver site-specific cleavage and labeling for therapeutic antibody fragment generation, fusion tag removal, and click chemistry-based protein modification, including IdeS/IdeZ for IgG fragmentation, SUMO protease, enterokinase, and Sortase A. Amerigo Scientific also supplies BenzoNuclease, a universal recombinant endonuclease that eliminates DNA and RNA contaminants to reduce sample viscosity and improve protein recovery before MS analysis, mitigating nucleic acid interference with downstream spectral data.

Amerigo Scientific’s product range caters to small academic labs conducting fundamental proteomic research through large biotech cohorts running high-volume therapeutic protein characterization programs.
