Frequently asked questions

Research use only. Not for human or veterinary use.

What is LL-37?

LL-37 is a synthetic 37 residue peptide with the molecular formula C205H340N60O53, a molecular weight of 4493 g/mol and CAS number 154947-66-7 (PubChem CID 16198951). Its sequence is LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES, and its name comes from the two leucine residues that open the chain and its length. Oasis Labs supplies it as a lyophilized powder at 99%+ documented purity for laboratory research use only.

Is LL-37 the same as cathelicidin?

Not quite. LL-37 corresponds to the C-terminal fragment of the human cathelicidin precursor protein hCAP18, so it is a part of that molecule rather than the whole of it. The precursor is considerably larger; the fragment Oasis Labs supplies is 37 residues, C205H340N60O53 at 4493 g/mol, CAS 154947-66-7. Published literature often uses cathelicidin loosely to cover the LL-37 fragment as well as the precursor, which is why researchers comparing sources should check the CAS number rather than the name. Supplied strictly as a research reagent. No human or veterinary use is described, supported or intended.

What has LL-37 been studied for in research settings?

Published research on LL-37 includes work on its membrane interaction behaviour measured in laboratory assay systems. Oasis Labs supplies this material strictly as a research reagent. No human or veterinary use is described, supported or intended.

What are the specifications for Oasis Labs LL-37 10mg?

SKU LL37-10MG. Supplied as a 10mg vial of lyophilized powder, white to off-white in appearance, at 99%+ documented purity by HPLC. Molecular formula C205H340N60O53, molecular weight 4493 g/mol, CAS 154947-66-7, 37 amino acid residues. Identity, purity and net content are documented per lot on the published Certificate of Analysis.

Where can researchers buy LL-37 with a published Certificate of Analysis?
