Stabilizing the Unstable: Sample Stabilization Approaches for Unstable Compounds in Biological Matrices

Life Sciences, Drug Discovery & Development, Laboratory Technology, Fundamental Research,
  • Friday, December 11, 2020

In order to obtain accurate and meaningful data, it is essential that the analyte of interest be sufficiently stabile in the sample matrix. The stability should be proven covering the entire sample lifecycle: beginning from the time of collection until the last reported analytical result. There are many biological fluids that laboratories analyze, including plasma, serum, whole blood, urine, cerebral spinal fluid (CSF), as well as tissues such as skin, lung and brain. Each of these matrices can present stability challenges due to their varied endogenous components that can either help maintain analyte stability or be the culprit for instability. This presentation will cover some of the factors that contribute to analyte instability as well as strategies that can be used during sample collection and handling to achieve stability prior to analysis.
