Custom glycopeptide & glycoprotein synthesis
Synthesis of homogenous glycopeptides and glycoproteins
The increasing importance of glycans in life science has led to a greater need for glycopeptides and glycoproteins that have controlled glycoforms, for applications such as peptide drug discovery, antibody development, and biomarker analysis.
GlyTech, Inc. has spent over 20 years developing a chemical glycosylation platform to meet this need which conventional cellular expression cannot fulfill. We provide chemical synthesis of homogeneous glycopeptides and small glycoproteins with full glycoform control, including glycan position, number, and structure. Our highly flexible platform allows us to custom synthesize glycopeptides and glycoproteins towards the exact requirements of your project.

Synthesis capabilities
Type of glycosylation
We can synthesize homogeneous glycopeptides and glycoproteins with any glycan(s) from our library.
- N-glycosylated peptides and proteins (asparagine-linked or cysteine-linked)
- O-glycosylated peptides and proteins (threonine-linked or serine-linked)
Designable glycoform
Our technology allows us to freely design the glycan pattern that we apply to a peptide or protein in terms of glycan position, structure, and number.
