Description

Application

When immobilized using an insoluble porous support matrix such as agarose, Cibacron Blue 3GA is used for affinity chromatography purification of enzymes.[1] This affinity has been attributed to a structural similarity between the dye and the natural ligands for proteins with cofactor binding domains.[2]

Biochem/physiol Actions

Cibacron Blue 3GA is an anionic anthraquinone dye. It acts as a P₂-purinoceptor antagonist[3] and inhibits stimulus-evoked glutamate release by rat brain cortical tissue.[4] Cibacron Blue 3GA inhibits OXA-1[5] and OXA-2 β-lactamases[6] and was used to observe the binding of ligands to OXA-1 β-lactamase by monitoring tryptophan fluorescence.
