Description
A single-component research material supplied for controlled research environments. LL-37 is the C-terminal cathelicidin peptide (human hCAP18 fragment), a 37-residue cationic α-helical sequence used in research investigating peptide–membrane interaction, antimicrobial peptide chemistry, and receptor-binding characterization in model systems.
Composition
• LL-37 (cathelicidin antimicrobial peptide, hCAP18 C-terminal fragment)
• Appearance: Lyophilized powder in a sealed research vial
Research Focus (non-clinical)
• Peptide identity and purity assessment via HPLC/LC-MS
• In-vitro characterization of cationic peptide–membrane interaction in bacterial and enveloped-particle model systems
• Receptor-binding and displacement assay development, including MRGPRX2 ligand characterization in cultured cell models
• Assay development and calibration for quantitative analysis of an α-helical cationic peptide
• Stability and solubility profiling of a lyophilized peptide under controlled laboratory storage conditions
Supplied exclusively to licensed professionals and qualified research institutions. Not for human use.
Documentation & Quality Assurance
Each lot is sourced through our verified global supply chain with emphasis on traceability and quality control. We work diligently to obtain and maintain third-party analytical reports and Certificates of Analysis for each batch — covering qualitative identity, percent purity, quantitative assay, heavy metals (ICP-MS) and microbial counts (TAMC/TYMC), as part of our ongoing quality process. These documents are reviewed internally and displayed as they become available. Independent third-party testing is also performed on select lots to confirm identity, purity, and alignment with our internal specifications.
Important Notice
LL-37 is sold exclusively for laboratory and research purposes. It is not approved for human use by the FDA or any regulatory authority.
This product is intended for laboratory research use only. It is not intended for human or veterinary use, and must not be used for diagnostic, therapeutic, or clinical purposes.
This material is not a drug, medical device, or dietary supplement, and has not been evaluated by the U.S. Food and Drug Administration.
Quality & Manufacturing
All materials are sourced from carefully vetted domestic and international manufacturing partners who follow quality systems consistent with ISO and cGMP principles. Each supplier is reviewed for reliability, documentation integrity, and transparency in testing.
We require a verified purity of 98% or higher and perform independent third-party batch testing to confirm that lots meet our internal specifications for identity, purity, and composition. Certificates of Analysis report qualitative identity and percent purity by UV-Vis, quantitative assay, heavy metals by ICP-MS, and total aerobic microbial (TAMC) and total yeast and mold (TYMC) counts. These are bioburden and composition panels for research quality assessment only; they do not imply suitability for human or veterinary use.
All research materials are sealed for integrity and packaged for stability during storage and transport from manufacturing through final delivery.
