Descrição geral
Package sizes are based on total solids content
Apoaequorin has a mol. wt. approx. 22 kDa, and contains a molecule of coelenterazine hydroperoxide as the chromophoric prosthetic group. Upon binding Ca2+, aequorin decomposes to apoaequorin, coelenteramide, and CO2, and emits light.
Ações bioquímicas/fisiológicas
A bioluminescent protein; can be used to measure physiological levels of calcium in serum and subcellular organelles down to 10 μM.
forma física
Contains buffer salts consisting mainly of sodium EDTA, pH 7.5

Highly purified histidine-tagged aequorin with a reactive cysteine residue (His-Cys4-aequorin) was obtained from the periplasmic space of Escherichia coli cells by nickel-chelate affinity chromatography and hydrophobic chromatography. The procedure yielded 40.3mg of His-Cys4-aequorin from 2L of cultured cells with over
