Description

Application

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

Biochem/physiol Actions

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