Beschreibung: Spin trap used in conjunction with Fe²⁺ to detect NO in brain, kidney, liver, and other tissues. Simultaneous direct measurement of NO* and pO₂ has been reported. A copper chelator, it has been used to quantitate copper in biological materials by ESR and is an inhibitor of superoxide dismutase, ascorbate oxidase, and other enzymes. Also used for colorimetric determination of small quantities of arsenic. Silver diethyldithiocarbamate has been used in cell culture.

Beschreibung: Oil Red O stains lipid materials and imparts red-orange color to the lipids. It also marks vacuoles, particularly observed in ALL-L3 (acute lymphoblastic leukemia) or Burkitt′s lymphoma/leukemia. Oil Red O staining is done on fresh samples, as alcohol fixation removes lipids.

Beschreibung: When immobilised using an insoluble porous support matrix such as agarose, Cibacron Blue 3GA is used for affinity chromatography purification of enzymes. This affinity has been attributed to a structural similarity between the dye and the natural ligands for proteins with cofactor binding domains.

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.

Hersteller Artikel Nummer : HT501320-9.5L

Beschreibung: Formalin solution, neutral buffered, 10% is the most commonly used fixative for light microscopy. It requires a relatively short period of fixation. It is suitable for the long-term storage of tissue. Once properly fixed, the tissue should be able to withstand the subsequent stages of tissue processing or staining.
