LL-37 Peptide for Sale: The Ultimate Guide to Human Cathelicidin LL-37

Welcome to Elite Peptide Supply, your trusted source for high-quality research peptides. This comprehensive guide explores everything you need to know about LL-37 peptide, the only human cathelicidin antimicrobial peptide. If you are looking for LL-37 peptide for sale, you have come to the right place.

What is LL-37 Peptide?

LL-37 is a unique antimicrobial peptide belonging to the cathelicidin family, and it is the only cathelicidin-type peptide found in humans . It is a naturally occurring host defense peptide encoded by the CAMP gene located on chromosome 3 . The inactive precursor protein, hCAP18, is secreted by immune cells and epithelial cells and is processed extracellularly to become the active LL-37 peptide .

This peptide plays a crucial role in the human innate immune system, acting as a first line of defense against invading pathogens. When you search for LL-37 peptide for sale, you are seeking a compound that has demonstrated remarkable versatility in scientific research.

It is characterized by its broad-spectrum antimicrobial activity and its ability to modulate immune responses, making it a subject of intense scientific interest .

Human Cathelicidin LL-37

As the only human cathelicidin, LL-37 stands out as a critical component of the body’s natural defense mechanism. Human cathelicidin LL-37 is stored in the granules of neutrophils and is released at sites of infection and inflammation . Its importance is underscored by conditions like Kostmann syndrome, where patients suffer from severe neutropenia and have extremely low levels of LL-37, making them susceptible to life-threatening infections .

This highlights the peptide’s essential role in maintaining health and fighting disease. Elite Peptide Supply provides LL-37 peptide for sale for researchers investigating this vital component of human immunity.

What Does LL-37 Do?

The question “What does LL-37 do?” has a multifaceted answer. LL-37 is a multifunctional host defense peptide with a wide range of biological activities .

Direct Antimicrobial Action: LL-37 exhibits potent activity against a broad spectrum of microorganisms, including Gram-positive and Gram-negative bacteria, fungi, and viruses . It works by disrupting the cell membranes of these pathogens, leading to their destruction. This makes it a promising candidate for research into combatting antibiotic-resistant strains .

Antifungal and Antiviral Properties: Research shows that LL-37 antifungal capabilities are significant. It can disrupt fungal membranes, suppress fungal growth, and attenuate fungal adhesion to host cells . Similarly, LL-37 antimicrobial peptide chart data would confirm its activity against various viruses by damaging their envelopes, preventing the spread of infection .

Immunomodulation: Beyond its direct killing ability, LL-37 modulates the immune system. It can bind and inactivate bacterial endotoxins like lipopolysaccharide (LPS), reducing inflammation. Conversely, it can also promote the recruitment of immune cells to sites of infection, demonstrating both anti-inflammatory and pro-inflammatory properties depending on the context .

Potential in Wound Healing: Human clinical trials have investigated the efficacy of topical LL-37 in wound healing. A study on hard-to-heal venous leg ulcers found that treatment with LL-37 was safe and well-tolerated, with the lower doses (0.5 and 1.6 mg/mL) showing a marked effect on healing rates .

Research on Cancer: Scientific literature explores the complex role of LL-37 in cancer, where it exhibits both anti-cancer and pro-cancer effects depending on the cancer type . This dual role makes it a fascinating subject for oncology research. When you buy LL-37 peptide from Elite Peptide Supply, you are accessing a peptide with wide-ranging research applications.

Why is LL-37 5mg Popular?

The LL-37 5mg formulation is a popular choice among researchers for several reasons. As a 5mg quantity provides a practical amount for a series of experiments without committing to a larger, more expensive supply, it offers an optimal balance for initial studies and dosage testing.

The concentration is suitable for creating various solutions for in-vitro or in-vivo research applications. Its popularity also stems from the fact that it allows researchers to evaluate the LL-37 peptide price effectively and manage their research budgets. For researchers looking to purchase high-quality LL-37 peptide for sale, the 5mg size is an excellent starting point.

LL-37 Dosing and Dosage Chart

Determining the appropriate LL-37 dosing is critical for research validity and safety. Clinical studies have used various concentrations depending on the application. For instance, in a clinical trial for wound healing, concentrations of LL-37 at 0.5, 1.6, and 3.2 mg/mL were applied topically twice weekly .

Interestingly, in that study, the lower doses (0.5 and 1.6 mg/mL) demonstrated superior healing efficacy compared to the higher dose or placebo, indicating a non-linear dose-response relationship.

An LL-37 dosage chart is often used in research to compare these concentrations and their effects. It is crucial to note that an LL-37 dosage calculator is not a substitute for professional research protocol design. If you are looking for LL-37 peptide for sale for research, Elite Peptide Supply recommends consulting the relevant scientific literature to establish appropriate protocols.

LL-37 Peptide Dosage and Frequency

The LL-37 peptide dosage and frequency are paramount in experimental design. As seen in the VLU trial, a frequency of twice-weekly applications was used for topical administration . The LL-37 peptide dosing strategy can vary significantly based on the route of administration (topical, injection, etc.), the model being studied, and the specific research objectives.

It is vital to establish a well-defined LL-37 dosage and frequency regime. Researchers purchasing LL-37 peptide for sale should design their protocols based on peer-reviewed studies and preliminary data, always prioritizing safety and methodological rigor.

LL-37 Sequence and Structure

The LL-37 sequence is well-characterized. The active form is a 37-amino acid peptide with a specific helical structure that is critical for its function . The peptide’s structure allows it to interact with and permeabilize microbial cell membranes . Understanding the LL-37 sequence and its three-dimensional conformation is key to comprehending its mechanism of action. The LL-37 antimicrobial peptide chart often highlights this sequence and structure, placing it within the broader family of antimicrobial peptides. The human cathelicidin LL-37 sequence is a fundamental piece of information for researchers synthesizing or studying this peptide.

LL-37 FDA Approval and Regulatory Status

A common question is about LL-37 FDA approval. It is important to state clearly that LL-37 is not FDA-approved for any therapeutic indication . Its classification and regulatory status are currently in flux. As of recent announcements, the FDA has indicated that certain peptides, including LL-37, will be considered for reclassification, potentially moving from Category 2 (restricted compounding) to a regulated access framework .

This shift aims to provide a legal and safe pathway for licensed compounding pharmacies to prepare these peptides for patients with a valid prescription. As of mid-2026, the regulatory mechanics are still in motion, with formal FDA guidance pending . For researchers and consumers, this means the legal landscape for obtaining LL-37 is evolving. Elite Peptide Supply offers LL-37 peptide for sale for research purposes, adhering to all applicable regulations.

 

LL-37 Side Effects and Safety

Understanding LL-37 side effects is critical for responsible research. The peptide is known to be cytotoxic to human cells, particularly at higher concentrations . Studies have shown that µM concentrations of LL-37 can cause cell shrinkage and reduce cell viability in various cell types .

However, research suggests that LL-37 primarily targets already infected or weakened cells, which may be a mechanism to limit the spread of infection .

In the clinical trial for venous leg ulcers, topical treatment with LL-37 was reported to be safe and well-tolerated, with no safety concerns regarding local or systemic adverse events .

This suggests that at appropriate doses and routes of administration, the risk of adverse LL-37 side effects can be managed. Anyone considering LL-37 peptide for sale should be fully aware of its potential cytotoxic effects and design research protocols to mitigate these risks.

LL-37 Peptide Benefits

The potential LL-37 peptides benefits are vast, fueling ongoing research.
