Beschreibung: Tetramethylrhodamine isothiocyanate Isomer R (TRITC) is the R isomer of tetramethylrhodamine isothiocyanate and is also known as 6-tetramethylrhodamine isothiocyanate. It is a strongly fluorescent compound soluble in ethanol, methanol, dimethylformamide, dimethylsulfoxide, and water. TRITC is a moderately-sized aminoxanthene dye carrying carboxylic acid and isothiocyanate substituents on the non-planar pendant phenyl ring. It forms a lipophilic cation in acidic pH and a hydrophilic zwitterion around neutral pH. The isothiocyanate group reacts with nucleophilic substituents (e.g., amino, hydroxyl, thiol) of biomolecules, providing the means of attaching a fluorescent label. TRITC also reacts with water and hydroxide ions and is unstable in aqueous solutions. TRITC is commercially available as a zwitterion or as a chloride.

Beschreibung: Acriflavine also interacts with HIF-1α (hypoxia-inducible factor 1 α) and HIF-2α, and thereby suppresses dimer formation of HIF-1 and transcriptional function. It also has negative effect on tumor growth and vascularization. Acriflavine also exhibits trypanocidal, antibacterial and antiviral activities.

Beschreibung: Eosin Y is a xanthene dye and is used for the differential staining of connective tissue and cytoplasm. In histopathology, it is applied as a counterstain after hematoxylin and before methylene blue. It is also used as a background stain, thereby giving contrast to the nuclear stains.

Beschreibung: N,N-Dimethyl-p-phenylenediamine dihydrochloride (DMPD) has been used in the HID-AB (high iron diamine-alcian blue) staining of intestinal tract samples. N,N-Dimethyl-p-phenylenediamine dihydrochloride (DMPD) is used for the determination of peroxidase. DMPD is converted into a red pigment of semiquinone nature. It is also used in the HID-AB (high iron diamine-alcian blue) staining procedures, which are used to differentiate between sialomucin and sulfomucin in the gastrointestinal tract.
