Beschreibung: Acridine Orange base (3,6-Bis(dimethylamino)acridine) is a cell-permeable fluorescent dye that binds to nucleic acids. It emits green fluorescence when bound to dsDNA and red fluorescence when bound to ssDNA or RNA. It is also known to be a positive solvatochromic dye. Acridine orange has also been used as a lysosomal dye. It is widely used to detect the presence of homeopathic potencies.

Beschreibung: 1-Methoxy-5-methylphenazinium methyl sulfate (MPMS) is a photochemically stable electron-transport mediator between NAD(P)H and tetrazolium dyes. The reduced form of MPMS converts tetrazolium salt to purple precipitate formazan. It is a very stable and non-enzymic electron carrier that mediates electron transfer by dehydrogenases in vitro to various electron acceptors such as tetrazolium dyes or the electrode of an enzymic electric cell.

Beschreibung: Pepsin is used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies. In immunohistochemistry (IHC), most commonly used fixatives such as formalin mask tissue antigens (cellular, membrane, and nuclear) by their intrinsic crosslinking. This masking results in poor or no staining in IHC. Pepsin digestion of FFPE tissue sections improves accessibility of antibodies to tissue antigens. Ready to use pepsin reagent, antigen retriever has been used for antigen unmasking in immunohistochemistry.

Beschreibung: 3,3′-dihexyloxacarbocyanine iodide (DiOC6) is a supravital lipophilic fluorochrome. This cationic dye is employed to stain mitochondria and endoplasmic reticulum in animal and plant cells. In addition, it acts as a very rapid, consistent and highly selective fluorochrome for endophytic ascomycetes in plant roots and liverworts. DiOC6 also facilitates the detection of different mitochondrial changes happening during early apoptosis.
