Endotoxin testing measures bacterial endotoxin contamination in a sample using the LAL method described in USP <85>. It is a standard analytical quality control check for research materials.
What testing does and does not do. Laboratory testing on this page is analytical quality control for research materials. A test measures what is in the sample that was sent: its identity, purity, quantity, or a specific contaminant. A certificate of analysis covers only that sample, on that date. It does not establish that a material is safe or effective, it does not approve any product for human or veterinary use, and no product or material referenced here has been evaluated by the Food and Drug Administration. All materials are for in-vitro laboratory research purposes only. Not for human consumption.
Disclosure: Peptide Stores Online lists these laboratories for information and comparison. Most listings are plain links and earn nothing. Where a laboratory link is an affiliate link, it is marked as a partner link next to the link itself, and Peptide Stores Online may earn a commission on orders placed through it, at no extra cost to you. Affiliate status never affects whether a lab is listed or how listings are ordered.
Endotoxin testing is destructive and usually needs a separate or extra vial. Budget for that when you plan how many vials to send. Results arrive on the lab’s standard clock, separate from any sterility culture clock.
Add-on prices in this directory run from about $100 to $300, most often $150 to $250.
An endotoxin result is one analytical measurement on one sample. It does not make a research material safe, approved, or suitable for any human or veterinary use, and this section never presents it that way.
