Incretin Receptor Pharmacology: GLP-1, GIP and Glucagon Receptors
GLP-1, GIP and glucagon receptors are class B1 G-protein-coupled receptors. They share architecture, they share a primary signalling route, and they are the targets behind mono-, dual- and triple-agonist research compounds. Understanding what distinguishes them clarifies why multi-receptor peptides are designed the way they are. Class B1 GPCRs Class
HPLC and Mass Spectrometry: How Peptide Purity and Identity Are Verified
Two analytical questions sit behind every research peptide: is this the right molecule, and how much of the vial is that molecule rather than something else? Mass spectrometry answers the first. Reversed-phase HPLC answers the second. Neither answers both, which is why a credible analysis reports both. Reversed-phase HPLC:
Storage and Stability of Lyophilised Research Peptides
Peptides are supplied lyophilised because dry powder is far more stable than peptide in solution. How that powder is handled between delivery and analysis determines whether your material still matches the certificate of analysis. Degradation is rarely visible, which is what makes it a problem: a partially degraded sample
How to Read a Certificate of Analysis for Research Peptides
A Certificate of Analysis (COA) is the document that separates a characterised research compound from an unknown powder. It is also the document most buyers skim without reading. This guide explains what each section actually tells you, and what its absence should tell you. What a COA is A
