BAPTA AM is cell-permeable version of BAPTA, a cell-permeable calcium chelator.

10x50 µg. Ex: 363 nm. Em: 512 nm. Soluble in: Water. Among the ratiometric calcium indicators, Fura-2 and Indo-1 are most commonly used. Fura-2 is excitation-ratioable while Indo-1 is emission-ratioable. Fura-2 is preferred for ratio-imaging microscopy, in which it is more practical to change excitation wavelengths than emission wavelengths. Upon binding Ca2+, Fura-2...

Ex: 354 nm. Em: 525 nm. Soluble in: Water. Although Fura-2 has been widely used as the preferred excitation-ratioable calcium indicator it has certain limitations, e.g., lower sensitivity compared to the single wavelength calcium dyes such as Fluo-8® and Cal-520®. AAT has recently developed Fura-8T to further improve the calcium response of Fura-2. Fura-8 has its emission...

This water-soluble biocytin hydrazide is used for the selective non-radioactive detection of glycoconjugates.

7-Hydroxycoumarin-4-acetic acid is used for labeling peptides and proteins to give blue fluorescence. It can also be used for labeling other biological molecules.

Calcium flux assays are preferred methods in drug discovery for screening G protein coupled receptors (GPCR). This ratiometric calcium assay kit allows homogeneous measurement of intracellular calcium changes caused by activation of G-protein-coupled receptors or calcium channels. Cells expressing a GPCR of interest that signals through calcium are pre-loaded with Fura-2 AM...

Fura Red is a visible light-excitable fura-2 analog that offers unique possibilities for ratiometric measurement of calcium ion in single cells by microphotometry, imaging or flow cytometry when used with single excitation, green-fluorescent calcium indicators. Ex: 458 nm. Em: 597 nm.

AAT Bioquest's iFluor(TM) dyes are optimized for labeling proteins, in particular, antibodies. iFluor(TM) 594 dyes have fluorescence excitation and emission maxima of 590 nm and 610 nm respectively. iFluor(TM) 594 family has the spectral properties similar to those of Texas Red(R) and Alexa Fluor(R) 594 (Texas Red(R) and Alexa Fluor(R) 594 are the trademarks of Invitrogen)....

Fluo-3 is essentially nonfluorescent unless bound to Ca2+ and exhibits a quantum yield at saturating Ca2+ of 0.14 and a Kd for Ca2+ of 390 nM.
