LL-37 (Human Cathelicidin) is a synthetic peptide with a molecular weight of 4493.33 g/mol and molecular formula C205H340N60O53. Supplied as a lyophilised solid, each batch is verified to ≥97% purity via HPLC analysis and accompanied by a Certificate of Analysis (COA).
LL-37 (Human Cathelicidin) is soluble in water and dilute acetic acid. For optimal stability, store the unopened vial at -20 °C, desiccated. Stable for up to 14 days at 2–8 °C in aqueous solution under sterile conditions.
Every compound we supply is synthesized in ISO-certified GMP facilities using automated solid-phase peptide synthesis, ensuring batch-to-batch consistency and accurate sequencing.
Each batch undergoes independent third-party testing — HPLC for purity verification (≥97%), mass spectrometry for identity confirmation, and endotoxin screening (<1 EU/μg). A full Certificate of Analysis ships with every order.
We offer free worldwide shipping with temperature-controlled packaging, anonymous checkout for your privacy, and responsive support from a team that understands research-grade compounds.
