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.

Beschreibung: Gram’s safranin solution, also known as Safranin T or Basic Red 2, is a ready-to-use staining solution that comprises 10% safranin in ethanol. Safranin is a basic, cationic, azine dye containing a planar, diaminophenazine chromophore, with a phenyl substituent attached to a ring nitrogen. The trimethyl cationic form of safranine is lipophilic, whereas the dimethyl forms are weakly hydrophilic. It is most notably used in bacteriology as a counterstain in Gram staining to differentiate between Gram-positive and Gram-negative bacteria.
