Terminal modifications
Acetylation and amidation may be used to adjust peptide properties or mimic biological termini.
Peptide Modifications
Peptide Modifications for Advanced Research Projects
Modified peptides are often required when standard linear peptides do not meet the functional, analytical or application-specific needs of a project. Serox GmbH supports a broad range of peptide modification formats for research, diagnostic, biotechnology and development workflows.

Common Peptide Modification Types
Modification requirements are reviewed according to sequence, position, compatibility and project application. Common modification categories include terminal modifications, functional labels, conjugation handles and structural formats such as cyclized peptides.
Labels and tags
Biotinylation and fluorescent labeling can support assay development, detection and binding studies.
Phosphorylation
Phosphorylated peptides support signaling, kinase and antibody-related research workflows.
Cyclization and PEGylation
Cyclization and PEGylation can be considered for specialized structural or application requirements.
Feasibility and Sequence Review
Not every modification behaves the same way in synthesis, purification or analysis. Serox reviews technical feasibility, sequence complexity and expected purification behavior before confirming a project route.

Discussion of target purity, scale and documentation
Quality Control for Modified Peptides
Modified peptides require careful analytical verification because the modification changes the expected molecular structure. HPLC and mass spectrometry help confirm purity and identity according to the agreed specification.
Identity check
Mass spectrometry supports confirmation of the modified peptide mass.
