Unsure if your sample type is suitable? Contact us and we'll confirm before you send.
UK researchers increasingly expect documented endotoxin data alongside purity and identity results, especially for samples used in cell-based assays or sensitive applications.
By adding independent LAL testing to your batch documentation:

View Current ServicesLAL (Limulus Amebocyte Lysate) testing detects bacterial endotoxins in samples. It uses a reagent derived from horseshoe crab blood cells that reacts with endotoxins, providing quantitative results in EU/mL (Endotoxin Units per millilitre). It's the gold standard method for pyrogen testing in research and pharmaceutical applications.
Yes, LPS testing and endotoxin testing are the same thing. LPS (Lipopolysaccharide) is the bacterial endotoxin molecule found in the outer membrane of gram-negative bacteria. When people say "endotoxin testing" or "LPS testing," they're referring to the same LAL assay that detects and quantifies lipopolysaccharide contamination. Both terms are used interchangeably in the peptide and research community.
Bacterial endotoxins can cause inflammatory responses and interfere with experimental results, particularly in cell culture and in vivo studies. Testing ensures your peptides meet acceptable limits for research use, provides confidence to end users, and creates documented evidence of quality for regulatory purposes.
Yes. PeptideVerify will offer combined testing packages that include HPLC purity analysis, LC-MS identity verification, and LAL endotoxin testing. This gives you a complete peptide quality profile in one certificate, saving time and providing a consistent format for your documentation.
Typically 0.5-1.0 mL of reconstituted peptide solution is sufficient for endotoxin testing alone. For combined testing with HPLC and LC-MS, we recommend sending 2-5 mg of peptide or the equivalent volume in solution. We'll confirm exact requirements when you place your order.
We can test against your specified limit or use standard research-grade limits (typically <0.25 EU/mL for most peptide applications). The certificate will clearly show your specification, the measured result, and pass/fail status.
LAL endotoxin testing launches through PeptideVerify in early 2026. Join the waitlist to be notified first and secure priority testing slots.
