Understanding LL-37: The Human Cathelicidin
LL-37 is a 37-amino acid peptide cleaved from the C-terminal end of the human cathelicidin protein, hCAP18. It is the sole member of the cathelicidin family expressed in humans and plays a multifaceted role in immune defense and cellular regulation.
Why LL-37 Matters in Research
– Antimicrobial Activity LL-37 disrupts bacterial membranes, making it valuable for studying host-pathogen interactions.
– Immunomodulation It influences cytokine release, chemotaxis, and inflammation.
-Wound Healing Research suggests LL-37 promotes angiogenesis and tissue repair.
– Cancer Biology: Investigated for its effects on tumor cells and the tumor microenvironment.
Molecular Characteristics
– Sequence LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES
– Molecular Weight Approximately 4.5 kDa
– Structure: Amphipathic alpha-helical peptide
– CAS Number: 2023788-19-2 (for reference)
The Critical Importance of Quality for LL-37
LL-37 is a challenging peptide to synthesize. Its length, hydrophobicity, and tendency to form secondary structures require advanced manufacturing expertise. Low-quality LL-37 may be truncated, misfolded, or contaminated—all of which invalidate research. https://shanghaiapeptides.com/

A: We provide a Certificate of Analysis (COA) via HPLC and Mass Spectrometry testing for every batch. You can request this before or after purchase through our website. ll-37 peptide for sale
Q: Do you ship to all 50 US states?
A: Yes. We ship to research institutions, laboratories, and wholesale partners throughout the United States.
Q: Can you accommodate bulk orders for wholesale distribution?
A: Absolutely. We offer competitive wholesale pricing for qualified partners. Contact our team through [shanghaiapeptides.com](https://shanghaiapeptides.com) with your volume requirements. ll-37 peptide for sale
Q: How should I store LL-37 upon receipt?
A: LL-37 should be stored at -20°C (freezer) immediately upon receipt, protected from light and moisture. Lyophilized powder is stable when stored properly. Avoid repeated freeze-thaw cycles. Reconstitute in appropriate buffers—LL-37 can aggregate in plain water.
Q: What buffer should I use for reconstitution?
A: For most applications, we recommend sterile phosphate-buffered saline (PBS) or 0.1% acetic acid. Avoid low-ionic-strength solutions which can promote aggregation. Contact our technical team for application-specific recommendations.
