About LL-37

LL-37 is the only human cathelicidin antimicrobial peptide and is widely used in immunology and innate-immunity research. Supplied as a lyophilized powder for laboratory investigations into innate immune signaling, host-defense pathway markers, and immunomodulatory mechanisms in controlled experimental models. Each batch is verified for identity and purity using HPLC and mass spectrometry. Supplied as: Lyophilized powder Purity: >95-99 (HPLC verified) Storage: Store desiccated at ?20�C for long-term. Short-term room temperature exposure (around 1 month) during shipping/handling is generally acceptable if kept sealed, dry, and protected from heat/light. Designation: FOR RESEARCH USE ONLY. Not intended for human or animal consumption.
