Bacterial endotoxin testing (BET) for injectable research peptides using Limulus Amebocyte Lysate (LAL) methodology. Fast turnaround with signed COA.
Gram-negative bacterial endotoxins are a critical safety concern for any product intended for injection or parenteral use.
Endotoxins can cause fever, inflammation, and septic shock when introduced parenterally — even trace levels matter.
Peptide synthesis, purification, and lyophilization steps can introduce endotoxin from equipment or reagents.
Research peptide distributors increasingly require endotoxin data to support responsible use documentation.
3–5 business days standard for endotoxin testing — one of our fastest turnarounds.
BET report with full method documentation.
Submitting takes less than 5 minutes. Most projects turn around in 5–10 business days from sample receipt.
Fill out our sample intake form — sample type, quantity, and timeline. We confirm turnaround and quote within one business day.
We'll send submission instructions and our San Diego shipping address. Most samples ship ambient or cold depending on stability requirements.
Results are delivered as a signed PDF COA within the agreed turnaround. Rush service (2–3 business days) available for urgent timelines.
There is no single regulatory limit for research peptides. Common industry thresholds are <1 EU/mg or <5 EU/mg depending on the product and route of administration. We test against your stated specification.
Yes. All BET assays include an IET to confirm the assay is valid for your specific sample matrix.
Typically 1–5 mg of lyophilized peptide or 0.1–1 mL of liquid formulation.
Submit your samples and receive an ISO 17025 accreditation pending Certificate of Analysis. Results in 5–10 business days.
