In our last blog post we had a look on the first approach to infer trueness from linearity in method validations by applying normalization. This can be used to determine trueness in case no alternative methods or impurities for spiking are available. Apart from normalization, another possibility to solve this problem exists, which will be highlighted today.
In today's blog, we’d like to address a quite common problem during method validations and by using a practical example showing possibilities to solve it.
Monoclonal antibodies (mABs) are immunoglobulin molecules that bind to the same epitope and have a variety of applications in medicine and healthcare (e.g. as drugs). Although therapeutic mABs are extremely favorable due to their specificity, they are heterogeneous due to their manufacturing process and hence provide a challenge for characterization.
In today’s small blog article, we will learn about bioanalytical method validation and its recent advancements. Bioanalytical method validation refers to validation of analytical methods that deal with analysis of an analyte in biological matrices (like urine, saliva, blood etc.). Validation of such methods for the quantitative determination of analytes (e.g. drugs under development or their metabolites) and biomarkers in a given bio-matrix are critical for the successful conduct of nonclinical and clinical pharmacology studies.
