Compound Recovery Determination Service
Analyte Recovery in ADME Studies
Analyte recovery is crucial in Absorption, Distribution, Metabolism, and Excretion (ADME) studies for accurate drug quantification in biological samples. It ensures reliable data on how a drug behaves within the body, guiding optimal dosage and therapeutic strategies. Effective analyte recovery methods are vital for identifying and minimizing analyte loss during various stages of sample preparation and analysis, resulting in more precise ADME profiles.
Compound / Analyte Recovery Service by LC-MS/MS at Creative Biolabs
Creative Biolabs specializes in providing robust analyte recovery services using LC-MS/MS bioanalysis to support ADME studies comprehensively. With over 20 years of experience, our team employs a rigorous protocol designed to identify and quantify the variabilities in analyte losses, facilitating high reproducibility and accuracy in data.
Protocol Highlights
We categorize potential analyte losses at various stages of sample preparation and analysis into four primary segments:
By systematically investigating these stages, our protocol can pinpoint where analyte losses occur, leading to optimized recovery methods. For example, issues such as nonspecific binding to labware or matrix effects like ion suppression can significantly alter recovery rates. By addressing these problems, we can ensure a more accurate reflection of drug concentrations in biological matrices.
