aequorin
A luminescent protein isolated from the jellyfish Aequorea which emits blue light in the presence of even minute amounts of calcium ion; injected intracellularly, it is used to measure free calcium ion transients within cells. SEE ALSO: fura-2, quin-2.

aequor·in (e-kworґin) a protein isolated from the jellyfish Aequora aequora, bioluminescent in proportion to the amount of calcium ions present and injected into cells to measure calcium concentration; now largely replaced by fluorescent dyes.
