• Appearance: Lyophilized powder in a sealed research vial
Research Focus (non-clinical)
• Characterization of LL-37 in antimicrobial activity assays
• Studies on immune modulation and inflammatory pathway signaling
• Evaluation in cell culture and tissue models related to epithelial repair
• Stability and solubility profiling under laboratory storage conditions
For qualified research professionals and institutional laboratories. Not for human use.
Documentation & Quality Assurance
Each lot is sourced through our verified global supply chain with emphasis on traceability and quality control.These documents are reviewed internally and displayed as they become available. Independent third-party testing is also performed on select lots to confirm identity, purity, and alignment with our internal specifications.
Important Notice
This product is intended for laboratory research use only. It is not intended for human or veterinary use, and must not be used for diagnostic, therapeutic, or clinical purposes.
This material is not a drug, medical device, or dietary supplement, and has not been evaluated by the U.S. Food and Drug Administration.
Quality & Manufacturing
All materials are sourced from carefully vetted domestic and international manufacturing partners who follow quality systems consistent with ISO and cGMP principles. Each supplier is reviewed for reliability, documentation integrity, and transparency in testing.
We require a verified purity of 99% or higher and perform independent third-party spot testing to confirm that select lots meet our internal standards for identity, purity, and composition. Where available, endotoxin testing results are included on Certificates of Analysis to verify laboratory purity; their inclusion is for research quality assessment only and does not imply suitability for human or veterinary use.
All research materials are sealed for integrity and packaged for stability during storage and transport from manufacturing through final delivery.

Certificate of Analysis
Every batch undergoes independent third-party laboratory analysis to verify identity, potency, and safety. Testing includes quantitative assay verification, heavy metals screening, and comprehensive microbial analysis.
View Certificate of AnalysisStorage Instructions
All products from Apex Health Performance are manufactured using a lyophilization (freeze-drying) process. This method is designed to maintain product integrity and allows vials to remain stable during shipping for approximately 3–4 months.
Once a vial is reconstituted with bacteriostatic water, it should be stored in the refrigerator to help maintain stability. Under these conditions, reconstituted material is generally considered stable for up to 30 days.
Lyophilization is a dehydration technique in which compounds are frozen and then exposed to low pressure. This causes the water in the vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure. This powder can be kept at room temperature until reconstitution.
Upon receipt, products should be stored away from heat and light. For short-term use, refrigeration at approximately 4°C (39°F) is suitable. For long-term storage (several months to years), vials may be placed in a freezer at approximately -80°C (-112°F). Freezing is the preferred method for preserving product stability over extended periods.

Cathelicidin LL-37-Induced Transcriptome of Human Keratinocyte Identifies Chemokine CXCL10 Link to T-Cell-Mediated Rosacea Pathogenesis through Jak1/STAT1 Pathway.
We sought to understand the molecular mechanisms of LL-37-mediated rosacea-like inflammation in an in vitro model of normal human epidermal keratinocytes. Gene ontology enrichment of biological processes revealed activation of cellular response to molecules of bacterial origin, response to chemokines, and cytokine-mediated signaling pathways, whereas Kyoto Encyclopedia of Genes and Genomes enrichment analysis revealed the activation of TNF signaling, IL-17 signaling, NF-kB signaling, and chemokine signaling among the most significant pathways.

The antimicrobial effect of antimicrobial peptides is typically slow; they can be rapidly biodegraded and often have non-selective toxicity and elaborate sequences. Here we report a short peptide that is activated by ultrasound, that shows high broad-spectrum antibacterial efficiency (>99%) against clinically isolated methicillin-resistant bacteria (specifically, Staphylococcus aureus, Escherichia coli, Staphylococcus epidermidis, Enterobacter cancerogenus and Pseudomonas aeruginosa) with 15 m

RESULTS: LL-37 bound multiple domains of the Spike protein and inhibited its interaction with the human angiotensin-converting enzyme 2 (hACE2) receptor . Up to seven LL-37 molecules were observed surrounding Spike, forming a halo-like structure that may block receptor engagement.

In mice with chronic UC, simultaneously introducing VHH and an antimicrobial peptide LL37 into EV (EV), then administering orally improved intestinal barrier, inflammation and microbiota balance, resulted in relief of UC-induced depression and anxiety. Collectively, we demonstrated that oral delivery of EV effectively alleviated UC in mice and TAT efficiently loaded biologics into EV to confer protection from degradation in the gastrointestinal tract.
