Product Description:

LL-37 is a synthetic peptide corresponding to a sequence derived from the human cathelicidin protein family. It is commonly utilized in biochemical and molecular research involving peptide-mediated signaling and interaction dynamics. In controlled laboratory settings, LL-37 is studied for its role in peptide–membrane interactions, signaling pathway analysis, and structure-function characterization under defined in vitro conditions. This material is supplied in lyophilized powder form and is intended strictly for in vitro research and analytical applications.

Research Applications:

LL-37 is utilized in controlled research environments to support investigation of:

• Peptide–membrane interaction dynamics in model systems
• Peptide-associated signaling pathway analysis in controlled experimental conditions
• Structure-function relationships of cathelicidin-derived peptide sequences
• Interaction profiling in microbial and cellular assay-based systems
• Stability, degradation, and analytical characterization in laboratory environments

All research applications are conducted in non-human, non-clinical experimental settings.

Storage and Handling:

• Store lyophilized material at −20°C (−4°F)
• After reconstitution, store at 2–8°C (36–46°F) and use promptly
• Avoid repeated freeze-thaw cycles
