Peptide Technical Topics
Six subject hubs collect our guides on peptide synthesis, modification, analytical testing, quality, procurement and applications. Each hub links to the articles in that cluster and to the matching service page.
-
Peptide Synthesis
How custom peptide synthesis works: solid-phase and liquid-phase methods, sequence feasibility, scale from milligrams to kilograms, purification and release testing.
-
Peptide Modification
Peptide modification methods explained: head-to-tail and disulfide cyclisation, stapled peptides, PEGylation, biotinylation, fluorescent labelling, phosphorylation and isotope labelling.
-
Analytical Testing
How peptide purity and identity are measured: reverse-phase HPLC, LC-MS, MS/MS sequencing, amino-acid analysis, water content and net peptide content. What each result does and does not prove.
-
Quality and Compliance
What a peptide certificate of analysis should contain, how batch traceability works, which documents to request before an audit, and how to interpret specification versus release results.
-
Procurement and Supplier Knowledge
How to buy custom peptides: what to include in an RFQ, what drives price and lead time, how supplier qualification works, and what to plan for shipping, customs and packaging.
-
Applications and Research
How peptides are used in cosmetic formulation, biomedical research, diagnostics and drug development, and which synthesis and documentation requirements follow from each application.
