Beschreibung: Fura 2-AM (Fura 2) is a calcium-specific ratio-metric fluorescent dye. It is also known as acetoxy-methyl-ester. In response to calcium ions, ratio metric dyes like Fura 2 changes their respective excitation or emission spectra. The intracellular calcium concentration is determined by the fluorescence emission ratio or excitation at distinct wavelengths. Fura 2 has an emission peak at 505 nm, and the excitation peak ranges between 340 to 380 nm and is the preferred calcium indicator.

Beschreibung: Auramine O has been used to study the cuticle/cutin in the epidermis of the pollen presenter in Vangueria infausta. Auramine O is used for the staining of acid-fast organisms, coccidia. Auramine O along with carbol generates brilliant yellow fluorochrome of tubercle bacilli. It is effective in detecting positive cases of tuberculosis. Auramine O binds to the mycolic acid in the bacterial cell wall. Certified for use by fluorescence microscopy in Churukian′s modification of Truant′s fluorescent method for acid fast bacilli on paraffin sections.
