Updates from across the peptide research industry, including science, regulation and market developments.
Two harmonised guidelines adopted in November 2023 describe analytical procedures as a lifecycle — from defining what a method must measure to validating and maintaining it. Here is what changed.
Read articlePeptides and proteins can change during storage through well-characterised chemical reactions and physical processes. Knowing these pathways explains why storage conditions and stability data matter for research materials.
Read articleA single purity percentage on a certificate of analysis summarises a chromatogram. Understanding which impurities it can and cannot reveal helps laboratories read analytical documentation critically.
Read articlePeptides occupy a space between small molecules and large biologics. A frequently cited review explains their advantages, their limitations and the strategies researchers use to overcome them.
Read articleIpamorelin is a synthetic pentapeptide described in 1998 as the first selective growth hormone secretagogue. Its original characterisation was carried out in animal models.
Read articleIn 2001 researchers showed that the KiSS-1 gene encodes peptides that activate the orphan receptor GPR54. The discovery reshaped research on neuroendocrine signalling.
Read articleSS-31 is a small synthetic tetrapeptide that associates with cardiolipin in the inner mitochondrial membrane. A 2014 review by its co-developer explains the chemistry and the experimental evidence.
Read articleMost peptides are encoded by nuclear DNA. MOTS-c, described in 2015, is a 16-amino-acid peptide encoded within the mitochondrial genome — a finding that opened a new area of research.
Read articleTirzepatide was developed as a single peptide acting on both GIP and GLP-1 receptors. Its 2018 discovery paper explains the design and the in vitro characterisation behind it.
