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.

Histo/Zyme is a stabilized proteolytic enzyme in buffered solution, used to unmask immunoreactive sites altered by fixation and/or the embedding process. Treatment with a proteolytic enzyme in immunohistochemistry (IHC) is required to digest excess linkages and expose the antigen. The use of Histo/Zyme results in superior staining over traditionally used enzyme pretreatments, such as pepsin and trypsin. Moreover, Histo/Zyme requires only a brief incubation at room temperature. Performing antigen recovery with Histo/Zyme will allow you to dilute the primary antibody 5 to 10 fold further and achieve optimal staining.

Carmine is a cochineal product usually furnished as an aluminum and calcium salt of carminic acid. Carminic acid is used for human-medical cell diagnosis and serves the purpose of the histological investigation of sample material of human origin. It is suitable for staining nuclei in histological sections. It is utilised in various staining methods including the procedure for detection of glycogen and mucous substances (Best′s carmine), for nuclear staining, or vital staining.
