Research guides
PEPTIDE BASICS
Introduction to Research Peptides
A plain-language overview of what research peptides are, how they are documented, and why laboratory context matters.
QUALITY AND TESTING
How to Read a Peptide Certificate of Analysis (CoA)
A section-by-section walkthrough of the Certificate of Analysis and what each field tells a researcher about a sample.
QUALITY AND TESTING
Understanding Peptide Purity and Identity Testing
Purity and identity answer two different questions, and understanding both is essential to interpreting peptide documentation.
LABORATORY HANDLING
Peptide Storage and Stability Basics
An overview of the laboratory factors that influence peptide stability and why documenting storage conditions matters.
PEPTIDE BASICS
Lyophilized Peptides Explained
What freeze-drying is, why peptides are supplied as lyophilized powder, and what to observe when documenting a vial.
LABORATORY HANDLING
Common Laboratory Handling Mistakes
A survey of frequent handling and documentation errors that can undermine reproducibility when working with research peptides.
QUALITY AND TESTING
HPLC, Mass Spectrometry, and Third-Party Testing
How the two core analytical methods complement each other and why independent testing adds confidence to documentation.
PEPTIDE BASICS
How Peptide Naming Conventions Work
A guide to amino acid codes, sequence notation, and salt forms so researchers can order and cite the correct material.
RESEARCH LITERACY
Preclinical Research Versus Human Clinical Evidence
Why preclinical findings and human clinical evidence sit at different levels and how to read each type critically.
