What 'Research Use Only' Actually Means
The phrase shows up on every vial and invoice, but what does it actually signify? A look at the research-use-only classification and what it means for handling.
Read overview →How Peptides Get Their Names: A Nomenclature Primer
From three-letter codes to trivial names and sequence shorthand. How peptide naming works, why one molecule can carry several names, and how to read the labels.
Read overview →Cyclic vs. Linear Peptides in Research
Open chains versus closed rings. How cyclization changes a peptide's shape and stability, the main ways chemists close a ring, and why labs care about the difference.
Read overview →Peptide Bonds Explained
The single covalent link that turns loose amino acids into a chain. How the peptide bond forms, why it's rigid and planar, and what that means for the molecule.
Read overview →Amino Acids: The Building Blocks of Every Peptide
The twenty standard amino acids, their shared backbone, and how their side chains shape the peptides built from them. A foundational look at peptide chemistry.
Read overview →Peptides vs. Proteins: What Actually Separates Them
Size, structure, and how the two classes are characterized in the lab. A look at where peptides end and proteins begin, and why the distinction matters analytically.
Read overview →What Are Research Peptides? A Laboratory Primer
A plain-language look at what research peptides are as molecules, how they differ from other compounds, and how laboratories handle them under controlled conditions.
Read overview →Mass Spectrometry and Peptide Identity: A Plain-Language Primer
HPLC tells you how pure a peptide is; mass spectrometry tells you whether it is the right molecule. Here is how the identity check works on a COA.
