Validated QPS Assays
The vast majority of today’s modern bioanalytical methods for pharmacokinetics, pharmacodynamics, and immunogenicity assessment are based on mass spectrometry and/or immuno-bioanalytical approaches. However, for a small but important number of compounds, LC MS/MS or LBA are less than satisfactory. A good alternative is Inductively Coupled Plasma Mass Spectrometry (ICP-MS). In ICP MS, the samples are ionized by an inductively coupled plasma (ionization source) and the ions of interest are separated, detected, and quantitated by a mass spectrometer.
The QPS Assay Finder contains a broad range of validated assays for all of your bioanalytical needs.
