For researchers engaged in critical studies of immunology, infectious diseases, wound healing, and cancer, the quality and reliability of the reagents used are paramount. Among the essential biomolecules, LL-37 peptide has emerged as a compound of significant interest due to its diverse biological activities. This guide provides researchers with key considerations for sourcing high-quality LL-37 peptide, ensuring the integrity and success of their experiments.

LL-37 is a human cathelicidin antimicrobial peptide, characterized by its 37 amino acid sequence (LLGDFFRKSKEKIGKEFKRIVQRIKDFLRNLVPRTES). Its CAS number is 154947-66-7. As a vital component of the innate immune system, LL-37 exhibits broad-spectrum antimicrobial activity and significant immunomodulatory functions. When procuring this peptide, researchers must prioritize purity, as even minor impurities can affect experimental outcomes and lead to misleading results.

The standard for purity for research-grade peptides like LL-37 is typically ≥95%, often verified by High-Performance Liquid Chromatography (HPLC). Reputable suppliers will provide a Certificate of Analysis (CoA) detailing the purity, identity, and other critical specifications of the peptide batch. It is also advisable to look for suppliers who conduct rigorous quality control measures and provide detailed technical data, including solubility and storage recommendations. Understanding these specifications is crucial before you buy LL-37 peptide.

When selecting a supplier, consider their expertise in peptide synthesis and their reputation within the scientific community. Factors such as consistent product quality, reliable delivery, and responsive customer support are vital. Manufacturers specializing in the synthesis of complex peptides are more likely to offer a product that meets the stringent demands of cutting-edge research. As a leading supplier, we understand these needs and ensure our LL-37 peptide is manufactured to the highest standards.

The price of LL-37 peptide can vary depending on the quantity, purity, and supplier. While cost is a factor, it should not be the sole determinant.
