LL-37 10mg (Antimicrobial Research Reagent)⁠

LL-37 Antimicrobial Reagent 10mg | Human Cathelicidin-Derived Peptide

LL-37 is a 37-amino acid, amphipathic alpha-helical peptide representing the active carboxy-terminal domain of the human cathelicidin antimicrobial protein (hCAP18). Secreted endogenously by epithelial cells and specific leukocyte populations, LL-37 serves a dual-action role in laboratory models, functioning both as a direct neutralizing agent against foreign membrane matrices and as a versatile immunomodulatory signaling coordinator.

Within preclinical immune modulation and cellular repair matrices, this high-capacity 10mg LL-37 vial provides investigators with stable baseline materials to analyze cell migration cascades. By engaging directly with Formyl Peptide Receptor 2 (FPR2) and purinergic receptors, the compound acts as an excellent testing model for exploring structural tissue restoration, vascular endothelial growth factors (VEGF), and innate cell deployment pathways in vitro.

Analytical Purity & Structural Verification

To guarantee structural integrity and reproducible performance parameters across long-term experimental series, this testing reagent is strictly validated:

• HPLC Purity Mapping: Checked via High-Performance Liquid Chromatography to verify a chemical purity threshold of ≥98.0%, mitigating the interference of salt residuals or sequence anomalies.
• Mass Spectrometry Precision: Mass-spectral profile mapping guarantees exact alignment with the canonical 37-amino acid structural formula.
• Vacuum Isolation: Every vial is finalized under negative atmospheric pressure inside a controlled laboratory space to limit ambient humidity exposure.

Experimental Core Mechanisms & Research Vectors

Preclinical assay profiles implementing LL-37 10mg focus extensively on several primary physiological fields:

• Membrane Disruption Mechanics: Observing the carpet-like electrostatic interactions that lead to structural thinning and permeabilization of lipid bilayer barriers.
• Chemotactic Signaling: Tracking the cellular migration rates of mast cells, neutrophils, and peripheral blood mononuclear cells via targeted receptor recruitment models.
• Angiogenesis & Tissue Proliferation: Mapping downstream signaling changes that promote endothelial cell proliferation and direct tubule formation in vascular models.

Laboratory Reconstitution & Storage Standards

To avoid peptide degradation, adherence to strict storage and reconstitution environments should be enforced:

• Lyophilized Solid Maintenance: Keep un-reconstituted glass vials inside a laboratory freezer unit calibrated at -20°C for long-term storage. Ensure protection against continuous ambient light arrays.
• Fluid Reconstitution: Allow the structural vial housing to naturally equalize with room temperature parameters before breaching the seal. Reconstitute slowly utilizing Sterile Bacteriostatic Water or standard saline. Swirl smoothly; do not subject the fluid mixture to aggressive mechanical vortexing.
• Reconstituted Lifespan Limits: Store the active fluid solution inside an enclosed refrigeration compartment at 2°C to 6°C. For optimal experimental accuracy, exhaust all measurement sampling steps within 10 to 14 days post-reconstitution.
