Notes from the laboratory bench
Compliance-first, jargon-light articles on Certificates of Analysis, HPLC purity, lyophilisation and cold-chain handling. Written for researchers, procurement teams and curious technicians.
Combination research literature — why researchers study multi-peptide protocols
Why and how research teams investigate combinations of two or more peptides in regulated laboratory settings — including how to interpret combination-study citations on the Spheres Peptides Education index.
GLP-1 receptor research — a compliance-first overview for UK laboratories
GLP-1 receptor agonists are prescription-only medicines in the UK and cannot be advertised to the public. This article sets out, in compliant language, why these compounds are studied in research settings and how Spheres Peptides handles GLP-1 enquiries.
Understanding HPLC purity testing — how 99 % purity is verified
What does it actually mean when a Certificate of Analysis reports 99.4 % purity? A plain-English walk-through of reversed-phase HPLC, peak integration and mass-spectrometric confirmation.
Cold-chain storage best practices for research peptides
Temperature, light and humidity are the three quiet enemies of peptide stability. A short field guide to handling, transport and storage of research peptides in a laboratory setting.
Lyophilisation 101 — why research peptides ship as freeze-dried powder
Lyophilisation is the process used to convert a peptide solution into a stable, transportable powder. Understanding why it is used — and how reconstitution should be approached in a research context — is fundamental for any laboratory working with peptides.
What is a Certificate of Analysis (COA) and why batch verification matters in peptide research
Every research peptide vial should carry a unique batch number tied to an independent Certificate of Analysis. Here is how COAs are produced, what they prove, and how to verify them before any laboratory work begins.
