What does FPA mean in BRITISH MEDICINE

FPA stands for Fluorescence Polarisation Assay which is a laboratory technique used to measure the binding affinity of molecules using fluorescent labels.

FPA can be applied in a wide range of research areas, such as drug discovery, protein interaction studies and molecular recognition.

FPA works by combining two components — an analyte molecule that carries one or more fluorescent labels and an acceptor molecule that binds with the label. When these two molecules bind together, they become more strongly polarized than when they are unbound, causing their fluorescence intensity to increase.

By measuring the amount of polarization achieved, researchers can determine how strongly the two molecules bind together and thus gain insight into their binding affinity. This information can be used to study protein-protein interactions or drug-target bindings among other things.

The accuracy of this method depends on several factors such as sample purity and signal-to-noise ratio but it generally provides good results if performed correctly. Furthermore, researchers have developed different strategies over time to increase the accuracy of this assay such as analyzing multiple samples at once or splitting up samples into smaller aliquots.
