Radiometric analysis

One of the oldest methods used for the quantitation of drug molecules is radiometric analysis. This generally involves quantitation of radiation from beta-emitting radioactive isotopes such as 14C, 3H or 32P. Radiometric analysis is one of the most precise, sensitive, and efficient detection methods; however, there are many technical and social challenges with using this […]

Ligand binding assays

Our discussions of various bioanalytical methodologies over the past few weeks has focused on chromatography and small molecule analysis. Today we are going to discuss a collection of methods that is commonly used for large molecules, such as peptides, peptides and macromolecules. These molecules are often called “biologics” because they are generally derived from endogenous […]
