A library of peptide research, organized by hub.
Five subject hubs: peptide science fundamentals, analytical quality, evidence standards, compound profiles by pathway, and regulatory science. Every article separates molecule-level evidence from product-level status.
Analytical
Methods for identity confirmation, purity assessment, and content determination.
Why Blend Testing Is Harder Than Single-Compound Testing
A blend is not validated merely because each component has been tested separately. The combined material creates new analytical and stability questions.
Read articleResidual Solvents in Synthetic Peptide Materials
Peptide synthesis and purification can involve multiple organic solvents, and trace residues require analytical methods designed specifically to detect them.
Read articleMass Spectrometry and Peptide Identity Confirmation
Mass spectrometry can provide powerful evidence of peptide identity, especially when combined with chromatographic separation and sequence-aware interpretation.
Read articleHPLC for Peptide Analysis: What It Can and Cannot Prove
HPLC is one of the most useful tools in peptide quality control, but a chromatogram must be interpreted within the limits of the method.
