LL-37 is a 37-amino-acid cathelicidin-derived antimicrobial peptide that also modulates innate immunity, wound healing and inflammation, making it a versatile subject in host-defense research. Its dual antimicrobial and immunomodulatory activities support studies in infection biology and regenerative medicine. The peptide is supplied as a white lyophilized powder at >=99% HPLC purity in a sealed vial. Complete documentation and flexible ordering are available for research groups. Researchers tend to reach for this cathelicidin peptide when they want an antimicrobial host-defense tool that also engages immune and wound-healing readouts, which sets it apart from simple antibiotic compounds. A good deal of the work centers on membrane-disruption assays and chemotaxis studies, where its amphipathic structure is the feature under test. For many groups, it enters the workflow as the reference cathelicidin in innate-immunity panels. Practical handling is straightforward: it reconstitutes in dilute buffer, and because activity is concentration-sensitive, we document purity per lot and can reserve identical vials so replicate conditions line up exactly. On the logistics side, this cathelicidin ships with HPLC purity documentation and reconstitution guidance, and it reconstitutes readily in dilute buffer for immune assays. Replicate-heavy designs can reserve one lot for consistency, and delivery is arranged within recommended conditions. Bulk options are available. We are a professional peptide supplier with in-house quality control, offering both small trial packs and bulk quantities at factory-direct prices. Every order is packed carefully and dispatched with tracking, and our team provides responsive after-sales support for research customers worldwide.
