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.

Beschreibung: 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.

Beschreibung: A dual-emission potential-sensitive probe that can be used to measure mitochondrial membrane potential. JC-1 is a green-fluorescent (λex 520 nm) monomer at low membrane potential. At higher potentials, JC-1 forms red-fluorescent (λem 596 nm ) "J-aggregates," which exhibit broad excitation and very narrow emission spectra. The ratio of red to green fluorescence of JC-1 is dependent only on membrane potential, and not influenced by mitochondrial size, shape, or density.

Beschreibung: Melanin is a ubiquitous and prominent pigment responsible for color of skin, hair and eyes. Melanin is classified into eumelanin and pheomelanin. Eumelanin is black to dark brown pigment and is present in black hair and retina of the eye. Pheomelanin is yellow to reddish brown pigment present is red hair and red feathers. Melanins are high molecular weight pigments synthesised from phenolic or indolic precursors and is widely present in animals, plants and microorganisms.
