LL-37 is a 37-residue synthetic peptide with a defined amino acid sequence and a relatively large peptide framework. Its final analytical profile may vary depending on salt form, counterion profile, residual moisture, manufacturing process, and batch-specific documentation.

Structural Characteristics

LL-37 contains a long-chain amino acid sequence composed of hydrophobic, polar, acidic, and basic residues. The sequence begins with two leucine residues, which is reflected in the LL-37 naming convention, and includes multiple charged side-chain regions distributed across the peptide structure.

Due to its length and amino acid composition, LL-37 may present distinct analytical characteristics compared with shorter peptides, including sequence-dependent chromatographic behavior, mass verification requirements, and solubility considerations. Exact molecular data, salt form, purity, and assay information should be verified against supplier documentation or a lot-specific certificate of analysis when available.

Research Use Disclaimer

LL-37 5mg is intended for laboratory research use only. It is not intended for human or animal consumption, clinical use, diagnostic use, food use, supplement use, cosmetic use, household use, or any application outside of controlled research environments.
