In liposomal characterization, common measurement obstacles can compromise data integrity: Incomplete separation of non-encapsulated (free) drug from liposomes, leading to overestimation of efficiency Drug leakage during the separation process (e.g., during centrifugation or dialysis), causing false low results Interference from lipid components during spectrophotometric or chromatographic detection Difficulty in quantifying drug encapsulation efficiency for unstable or low-abundance cargoes Our encapsulation efficiency measurement services are specifically engineered to tackle these challenges by: Employing optimized separation techniques (e.g., Gel Filtration, Spin Columns, Dialysis) tailored to the drug's leakage profile Utilizing high-sensitivity HPLC/UPLC or LC-MS methods to quantify both loading efficiency and encapsulation efficiency accurately Validating lysis protocols to ensure complete release of the entrapped drug for total recovery measurement Providing detailed reports on how to calculate encapsulation efficiency with raw data support for R&D documentation By addressing these analytical challenges, BOC Sciences empowers researchers to validate their formulation processes with confidence
