In vitro study | The fluorescence of Calcein Blue (CB) is quenched by the Fe 2+ ion in the Calcein Blue-Fe 2+ complex. When dopamine is added to a solution of the Calcein Blue-Fe 2+ complex, a dopamine-Fe 2+ complex is formed as the result of a ligand exchange reaction between Calcein Blue and dopamine which permits the fluorescence from Calcein Blue to be recovered. The fluorescence intensity at the wavelength of 440 nm (at the excitation wavelength of 340 nm) is found to be proportional to the concentration of the dopamine added to the Calcein Blue-Fe 2+ complex solution, which permits dopamine to be quantitatively determined. The Calcein Blue-Fe 2+ complex shows a high selectivity for dopamine among the catecholamines and related compounds examined. |

overview | the chemical name of calcein blue (CaleCinblue) is 4-methyl umbelliferone -6-methyl iminodiacetic acid, which is a newly developed reagent applied abroad in recent years. at present, it is only seen in the reagent catalogues of a few manufacturers in the United States, Switzerland and West Germany. Shanghai Chemical Reagent Procurement and Supply Station should be required by the relevant domestic units to introduce the trial. Calcein blue is a colorless crystalline powder, easily soluble in alkaline solution, and produces long-lasting blue fluorescence, slightly soluble in water, ethanol and acetone. |
use | calcein blue can be used as a metal fluorescent indicator, calcium can be titrated by EDTA complexation at high pH, copper, nickel and diamond can be titrated by complexation at low pH, and can also be used for the study of t-RNA binding to heavy metals and as a fluorescent marker of bone. |
biological activity | Calcein Blue is an impermeable membrane fluorescent dye, which is a coumarin derivative containing iminodiacetic acid structure. Calcein Blue is also a metal fluorescent discoloration indicator. |
