Glycobiology
Glycans Decide Whether A Biologic Works.
Glycosylation is a critical quality attribute – it shapes potency, half-life, immunogenicity and biosimilar comparability. Krishgen gives you the enzymes, dyes and analytical tools to release, label and profile every glycan in your molecule, from discovery bench to GMP release.
A glycan profile is a fingerprint your regulator reads.
For monoclonal antibodies, fusion proteins, biosimilars and emerging cell & gene therapy vectors, the attached sugar structures are not a detail — they govern how the molecule behaves in the body and whether it clears review. Four reasons it sits on every characterisation plan.

Effector Function
Core fucosylation and terminal galactosylation tune ADCC and CDC. Small shifts in the Fc glycan change how strongly an antibody recruits the immune system.
Immunogenicity
Non-human glycans such as α-Gal and NGNA can trigger immune responses. You need to detect and quantify them before they reach a patient.
Half-life & Clearance
Sialylation and exposed mannose drive serum half-life through receptor-mediated clearance, directly shaping dose and pharmacokinetics.
Biosimilar Comparability
A biosimilar must match the reference glycan map lot after lot. Released-glycan profiling is the evidence regulators expect in the dossier.
Our Own Recombinant Glyco-enzymes & Dyes

Krishzyme™ 2-AB Labelling Dye (KPGF-401)
2-Aminobenzamide fluorescent label for released glycans, validated for HILIC-(U)HPLC, WAX-HPLC and MALDI-MS detection workflows.
KRISHZYME™ Glycosidase & Labelling Range (Full panel)
The complete in-house endo- and exoglycosidase panel plus labelling and clean-up reagents for building a full release-to-profile method. Bulk and OEM formats on request.
We Supply Every Step
Glycan analysis is a genuine sequence — and each stage maps to a defined family of Krishgen reagents and tools. Build a complete released-glycan method without juggling four vendors.
The Glycan Characterisation Workflow
Cleave N- and O-linked glycans from the protein backbone with recombinant glycosidases under native or denaturing conditions.
Trim defined residues with exoglycosidase panels to confirm linkage and sequence, then clean up for downstream analysis.
Tag released glycans with fluorophores for sensitive detection by HILIC-UHPLC, WAX-HPLC and MALDI-MS.
Separate, quantify and identify each glycan against standards and controls for release-grade quality data.
