HPLC Peptide Purity Explained: What >99.5% Means for Laboratory Characterisation
HPLC peptide purity is one of the most quoted figures on research-peptide documentation—and one of the easiest to over-interpret. A percentage on a Certificate of Analysis (COA) is a method-dependent chromatographic result. It is laboratory characterisation language, not a clinical-grade slogan and not a substitute for identity confirmation. This article explains, in plain UK laboratory […]
Mitochondrial Peptides in Focus: MOTS-c Research From Cell Models to Human Observational Studies
For most of modern biology textbooks, mitochondrial DNA was cast as a compact parts list: a handful of respiratory-chain proteins, transfer RNAs, and ribosomal RNAs. Then short open reading frames began to complicate the story. Among the molecules that emerged from that rethink is MOTS-c—a 16-amino-acid mitochondrial-derived peptide (MDP) that laboratories now treat as a […]
Copper Peptide Research Updates: GHK-Cu From Laboratory Models to Topical Wound Studies
Few research reagents have a paper trail as longand as carefully layered—as the copper-binding tripeptide GHK-Cu. For decades, laboratories have used the Cu(II)–glycyl-L-histidyl-L-lysine complex to ask questions about copper coordination chemistry, extracellular-matrix gene programmes, and how small peptides behave in cell and tissue models. The story is not a product pitch. It is a research […]
