LL-37 is the only human bactericidal peptide antimicrobial peptide, derived from the hCAP18 protein. It is a cationic, amphiphilic α-helical peptide consisting of 37 amino acids, with extensive immunomodulatory and host defense functions.
CAS Number: 154947-66-7
It exhibits strong antibacterial activity against Gram-positive and Gram-negative bacteria, fungi, and enveloped viruses. In addition to directly killing microorganisms, LL-37 also regulates inflammation, promotes wound healing, regulates the recruitment of immune cells, and supports tissue repair. It is widely studied in immunology, dermatology, infection research, and mucosal defense.
Production:
It is manufactured through solid-phase peptide synthesis (SPPS), then purified and freeze-dried to obtain the final product.
Note: This product is synthesized chemically. It is for research use only. Not for human use.

1. How to place an order?
Send me a message to tell me how many quantities you need, and I will calculate it for you.
2. What is the delivery time and transportation method?
We will deliver the packages via USPS, FEDEX, DHL parcels and UPS express. You can choose freely. After receiving the payment, it will take approximately 5 to 9 days to reach your address.
3. How to preserve the peptides after receiving them?
Peptides in powder form can be transported at room temperature through vacuum packaging, while dissolved peptides need to be refrigerated at 2°C - 8°C. For long-term storage, peptides should be stored in powder form, at -20°C or -80°C, in a sealed container with desiccant. This can minimize the degradation of the peptides to the greatest extent.
