Regeneration of the photoprotein aequorin

Nature, 1975
THE photoprotein aequorin (molecular weight about 30,000) isolated from the bioluminescent jellyfish Aequorea aequorea1–3 emits blue light (λm a x 470 nm)4 by an intramolecular reaction in aqueous solution when Ca2+ is added, in the presence or absence of molecular oxygen1. This reaction has been postulated5 to follow the scheme in (Fig.

Microinjection of calcium into droplets of aequorin

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1975
Abstract Calcium ions were microinjected, ionophoretically or by pressure, into droplets of the photoprotein aequorin. For pulses less than about 1 s in duration, the amplitude and rate of rise of the light emitted as a result of the combination of calcium with aequorin, were directly proportional to the ionophoretic current flowing ...

Interaction of Immobilized Avidin with an Aequorin–Biotin Conjugate: An Aequorin-Linked Assay for Biotin

Analytical Biochemistry, 1997
Biotinylated recombinant aequorin was used in the development of a heterogeneous bioluminescence binding assay for biotin. This assay is based on a competition between a biotinylated aequorin conjugate and biotin for the binding sites of avidin immobilized on solid particles.

The effect of alcohols on aequorin luminescence

Biochimica et Biophysica Acta (BBA) - General Subjects, 1986
The effect of alcohols from ethanol to octanol on aequorin luminescence was biphasic; enhancement of both peak light and total photon yield at low concentrations, and inhibition of these parameters at high concentrations. The potency of alcohols to exert these effects was in the same order as the oil/water partition coefficients of the alcohols.

Aequorin: Its ionic specificity

Biochemical and Biophysical Research Communications, 1972
Abstract The specificity of the cation-aequorin luminescent reaction was investigated. Contrary to present belief, this reaction was not specific for Ca 2+ and Sr 2+ . Over a dozen cations were capable of eliciting light emission from aequorin. Although these cations are not normally present in significant amounts in biological fluids, the present ...
