Pyrogen
Any substance that causes fever when introduced into the body. Endotoxins are the most common pyrogens in pharmaceutical products. Peptides must be tested and confirmed to be pyrogen-free.
Frequently Asked Questions
What is Pyrogen?
Any substance that causes fever when introduced into the body. Endotoxins are the most common pyrogens in pharmaceutical products. Peptides must be tested and confirmed to be pyrogen-free.
Why is Pyrogen important in peptide research?
Pyrogen is a foundational concept in peptide science. Understanding peptide chemistry helps researchers and practitioners evaluate peptide quality, predict stability, and make informed decisions about storage, reconstitution, and formulation.

Endotoxin
A toxic component of gram-negative bacterial cell walls (lipopolysaccharide). Endotoxin contamination in peptide preparations can cause fever, inflammation, and sepsis. Pharmaceutical-grade peptides are tested to be below endotoxin limits.
Endotoxin testingLaboratory analysis (typically Limulus Amebocyte Lysate or LAL test) to detect and quantify bacterial endotoxins in peptide products. FDA limits are typically <5 EU/kg body weight for injectable products.
