生物活性

Calcein Blue, a membrane-impermeant fluorescent dye, is a coumarin derivative that contains an iminodiacetic acid structure. Calcein Blue is also a metallofluorochromic indicator[1][2][3].

体外研究
(In Vitro)

The fluorescence of Calcein Blue (CB) is quenched by the Fe2+ ion in the Calcein Blue-Fe2+ complex. When dopamine is added to a solution of the Calcein Blue-Fe2+ complex, a dopamine-Fe2+ 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-Fe2+ complex solution, which permits dopamine to be quantitatively determined. The Calcein Blue-Fe2+ complex shows a high selectivity for dopamine among the catecholamines and related compounds examined[1].

Cell Assay

The recommended final working concentrations is usually between 1 and 10 μM to minimize potential artifacts. Generally, 15 minutes to 1 hour is sufficient for cellular uptake and processing of the dyes. A stock concentration of 5 mM 4-methylumbelliferone-8- methyliminodiacetic acid, commonly known as calcein blue is prepared in 0.1 M potassium hydroxide, and the pH is neutralized using 0.1 N hydrochloric acid. The calcein blue stock prepared is diluted to 200 μM (working stock) in DPBS and stored for further use. A concentration of 10 μM calcein blue is prepared from the working stock by diluting in DPBS. From this, 200 μL is added to a 96-well plate and the excitation/emission (Ex./Em.) maximum is determined using the micro-plate reader[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
