Scintillation proximity assay, commonly known as SPA, is a type of technology that is used to assay development and biochemical screening which permit the rapid and sensitive measurement of a broad range of biological processes in a homogeneous system. The type of beads that are involved in the SPA are microscopic in size and within the beads itself, there is a scintillant which emits light when it is stimulated. Stimulation occurs when radio-labelled molecules interact and bind to the surface of the bead. This interaction will trigger the bead to emit light, which can be detected using a photometer.

Famous quotes containing the words proximity and/or assay:
“The triumphs of peace have been in some proximity to war. Whilst the hand was still familiar with the sword-hilt, whilst the habits of the camp were still visible in the port and complexion of the gentleman, his intellectual power culminated; the compression and tension of these stern conditions is a training for the finest and softest arts, and can rarely be compensated in tranquil times, except by some analogous vigor drawn from occupations as hardy as war.”
—Ralph Waldo Emerson (1803–1882)
“The lyf so short, the craft so longe to lerne,
Th’ assay so hard, so sharp the conquerynge,
The dredful joye, alwey that slit so yerne;
Al this mene I be love.”
—Geoffrey Chaucer (1340–1400)
