Practical, no-hype guides for people who handle research peptides in the lab — how to read a certificate of analysis, reconstitute and store compounds, buy within the EU, and understand the literature behind the catalog.
Melanotan II and the Summer Research Season: Receptor Biology, Sample Stability, and Reading a COA
Melanotan II returns to the spotlight of research attention every summer. See the molecule through laboratory eyes: receptor biology, measurable melanogenesis, sample stability in heat, and the checkpoints of a trustworthy certificate of analysis.
Read articlePeptide vs. Protein vs. Hormone: Where Chain Length Ends and Role Begins
Peptide, protein, and hormone are answers to two different questions — how many amino acids a chain carries, and what role the molecule plays in the body's signaling. An overview of the boundaries, three-dimensional structure, the overlapping set of peptide hormones, and how correct classification translates into buying laboratory samples.
Read articleReading an Amino Acid Sequence Step by Step: How to Decode the Notation on a COA Certificate
The amino acid sequence on a COA certificate is a molecule's identity compressed into a handful of letters. Learn to decode it correctly — from the reading direction through terminal modifications to cross-checking the mass from mass spectrometry.
Read articleThe Peptide Bond: From Amino Acid Condensation to Sample Stability in the Lab
The peptide bond is the amide linkage that condenses amino acids into the backbone of every peptide. Understand its chemistry from resonance to hydrolysis, and learn how to protect sample stability in the laboratory.
