Peptide-Lipid Interaction Analysis Service is a specialized technical service designed to systematically investigate the interaction characteristics between peptide molecules and lipids. Through both quantitative and qualitative approaches, this service examines binding modes, affinity, kinetic parameters, and conformational changes associated with peptide-lipid interactions. It supports researchers in elucidating the functional mechanisms and membrane-targeting properties of bioactive peptides, with broad applications in membrane-active peptide design, drug delivery system development, antimicrobial mechanism studies, and membrane biology research.
Peptide-Lipid Interactions refer to reversible, non-covalent binding events between bioactive peptides and lipid membranes or individual lipid molecules, typically mediated by electrostatic forces, hydrophobic interactions, hydrogen bonding, and other weak forces. These interactions play crucial roles in biological processes such as membrane recognition, transmembrane transport, signal transduction, immune modulation, and membrane protein regulation.
In living systems, the cell membrane serves not only as a structural barrier but also as a dynamic functional platform. Certain natural or synthetic functional peptides-such as antimicrobial peptides, cell-penetrating peptides, and signaling peptides-can directly interact with lipid membranes to mediate cellular responses or modulate membrane structure and function. Therefore, systematically studying the mechanisms of peptide-lipid interactions is of great significance for understanding membrane-related biological processes, developing membrane-targeted therapeutics, and optimizing delivery platforms.

Sample Submission Suggestions
Sample Types:
It is recommended to provide high-purity (>95%) synthetic peptides in powder or lyophilized form. Lipid samples can be submitted as liposomes, phospholipid mixtures, or defined lipid compositions with specified ratios.
Storage and Shipping:
Peptide samples should be stored dry and protected from light, and shipped on dry ice. Lipid samples are recommended to be frozen at −80 °C and transported using dry ice.
Additional Notes:
We recommend contacting us prior to sample submission for detailed and tailored sample preparation guidelines.
