Peptide Science & Quality

What a legitimate Certificate of Analysis should contain, why batch-specific COAs matter, and how to request one from Alluvi Peptides.

How HPLC analysis works and why it is the gold standard for verifying peptide purity in research supply.

Half-life determines dosing frequency, washout periods, and the temporal dynamics of receptor engagement in peptide research. This guide explains the concept, degradation mechanisms, half-life extension strategies, and study design implications.

A clear explanation of peptide bond chemistry — how peptide bonds form, their unique structural properties, hydrolysis stability, and why this chemistry matters for interpreting research peptide behaviour and HPLC data.

A complete guide to reading and interpreting Certificates of Analysis for research peptides — covering every CoA field, HPLC and MS data interpretation, net peptide content, and red flags to watch for.

The ten most common reconstitution errors in peptide research — from opening cold vials to ignoring net peptide content — with practical corrections for each. Essential reading for any peptide lab.

A comprehensive laboratory guide to peptide storage and stability — covering degradation pathways, lyophilised vs reconstituted storage, freeze-thaw best practices, and sequence-specific considerations.

Peptide purity is fundamental to reproducible research. This guide explains what HPLC purity means, types of synthesis impurities, how to read a CoA, and purity thresholds for different research applications.

A practical research guide to lyophilisation — why peptides are freeze-dried, how the process preserves them, and a step-by-step protocol for reconstitution and storage in laboratory settings.
