Establishment of LC-MS/MS Methodology for the Determination of Rapamycin Concentration in Rat Whole Blood

The establishment and validation of methods for testing biological samples are crucial steps in pharmacokinetic studies. Currently, several methodological reports have been published on the detection of rapamycin plasma concentrations.

The objective of this study was to explore an effective method for detecting rapamycin in rat whole blood biological samples.

In this study, we designed a rapid, sensitive, and specific liquid chromatograph-mass spectrometer/mass spectrometer (LC-MS/MS) methodology for detecting rapamycin in rat whole blood biological samples. We comprehensively validated the specificity, linear range, lower limit of quantification (LLOQ), precision, accuracy, recovery, and stability of this method.

The findings of this study confirmed the successful implementation of LC-MS/MS for the detection of rapamycin, demonstrating its sensitivity, specificity, and reliability in quantitative analysis. This method ensures the accuracy and reliability of subsequent study data through our validated LC-MS/MS approach.

The results demonstrated the successful implementation of an LC-MS/MS method for sensitive, specific, and reliable quantitative analysis of rapamycin in rat whole blood samples. This method ensures the accuracy and reliability of subsequent study data.

The importance of this study lies in the successful establishment of a rapid, sensitive, and specific LC-MS/MS method for detecting rapamycin concentration in rat whole blood, ensuring the accuracy and reliability of subsequent research data. This provides a crucial tool and foundation for further understanding the metabolism and pharmacological effects of rapamycin in vivo, aiding in the advancement of drug research and clinical applications in related fields.
