Description

Immunoliposomes-Carboxylic Acid (PEGylated), Lyophilized Powder are advanced liposomal drug delivery systems that incorporate both polyethylene glycol (PEG) and carboxylic acid groups on their surfaces. This combination enhances their stability, circulation time, and biocompatibility while providing a functional handle (carboxylic acid group) for further chemical conjugation. The carboxylic acid groups serve as reactive sites for coupling with a variety of targeting ligands, including antibodies, peptides, and other biomolecules. Through activation with reagents such as carbodiimides (e.g., EDC/NHS), these groups enable the formation of stable amide bonds with primary amines, allowing precise functionalization under mild conditions. The PEGylation of these liposomes introduces a hydrophilic corona that minimizes aggregation, reduces immunogenicity, and enhances systemic circulation.
