Free-acid composition; the counterion is confirmed for the accepted order.
These identifiers describe the catalog material. The molecular weight shown is the average mass calculated from the molecular formula above, cross-checked against the PubChem record where one exists. The purity figure above is the specification printed on the packaging, not a result for any particular lot — batch-specific analytical documentation is confirmed for the actual item or accepted order. See Quality control. The pre-classification result number refers to the commodity classification issued for this material by the Hong Kong Trade and Industry Department under the Import and Export Ordinance (Cap. 60).
Planning work with this material
Distinguish full-length LL-37 from fragments and analogs by confirming sequence, termini, and counterion before ordering. The purchasing laboratory must independently define and validate controls for preparation conditions and containers.
Record package condition and lot details at arrival. Quarantine any item that conflicts with the accepted order documentation.
Documentation and order review
Availability, product identity, listed quantity, price, packaging, transport terms, storage information, and any supporting analytical documents are confirmed for the actual item or accepted order. Request the information your project requires before purchasing; a general catalog page cannot replace an order-specific specification or certificate.
- Confirm purchaser eligibility, destination rules, permits, and institutional approvals.
- Define identity and analytical acceptance criteria before the material is received.
- Inspect the package, identifier, quantity, lot information, and documents on arrival.
- Maintain controlled access, storage, preparation, traceability, and disposal records.
