Confirm the exact substance

LL-37 is a 37-residue amphipathic peptide. Synthetic material should be checked for sequence and aggregation behaviour, which affect handling.

What the review will ask

Ask about the intended application. Immune-modulating research claims should not be presented to patients as proven outcomes.

  • State the facility type, destination state and intended transaction. Do not send patient information.
  • Expect product- and lot-specific documentation to be requested before any material is accepted.
  • A listed price is a reference estimate. Availability, labeling, shipping and terms are confirmed in writing only after review.

Purchasing questions

Is LL-37 used in approved therapies?

No approved therapy uses synthetic LL-37. Published work is largely laboratory and early-stage research.

Request more than an antimicrobial label

FDA describes insufficient safety information and peptide-characterization concerns for cathelicidin LL-37. An antimicrobial research description is not a verified clinical indication.

Documentation to request

Obtain sequence identity and formulation-specific documentation; ask how aggregation and impurities are characterized for the exact material.

Regulatory context: FDA: substance-specific safety concerns. Source reviewed . This source does not verify the identity, testing or availability of our catalog references.
