Introduction Peptides—short chains of amino acids—serve as signaling molecules, enzyme substrates, and structural motifs across biology. Their high selectivity, tunable half-life, and well characterized synthesis methods make them indispensable in modern laboratories. This guide summarizes fundamental concepts, experimental considerations, and best practices so researchers can design, source, handle, and analyze peptides with confidence. Peptide Fundamentals
Introduction Two principal strategies dominate peptide production: solid-phase peptide synthesis (SPPS) and solution-phase synthesis (SPS). Each offers distinct advantages in scalability, speed, and purity control. This primer compares workflows, chemistries, typical pitfalls, and selection criteria. Core Chemistry Both methods form amide bonds between activated carboxyl and amine groups. Protecting groups (Fmoc, Boc) prevent side reactions;
Peptides are at the foundation of modern biochemical research. Understanding what they are, how they are synthesized, and how they are regulated in terms of use is essential for anyone working with them in a laboratory or preclinical setting. What Are Peptides? Definition & Structure Peptides are short chains of amino acids linked together by
Introduction Analytical verification underpins reproducible peptide science. High-Performance Liquid Chromatography (HPLC) assesses purity and retention behavior, while Mass Spectrometry (MS) confirms molecular identity with high specificity. This guide outlines practical method selection, instrument parameters, and interpretation tips. HPLC Basics Reversed-phase (C18/C8) is standard for peptides. Typical mobile phases use water/acetonitrile with volatile modifiers (0.05–0.1% formic
