Endotoxin testing

Laboratory 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.

Frequently Asked Questions

What is Endotoxin testing?
Laboratory 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.
Why is Endotoxin testing important in peptide research?
Endotoxin testing relates to the tools and quality standards that ensure peptide safety and efficacy. Proper equipment and testing are critical for accurate dosing, contamination prevention, and verifying peptide authenticity.

Related Terms

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.

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.

Certificate of analysis

A document from a laboratory confirming the identity, purity, and quality of a peptide batch. Should include HPLC purity percentage, mass spectrometry confirmation, and endotoxin levels. Essential for verifying peptide quality.

Third-party testing

Independent laboratory analysis of a peptide by a facility not affiliated with the manufacturer. Provides unbiased verification of purity, identity, and absence of contaminants. A hallmark of reputable peptide suppliers.
