AdipoGen Nitrotetrazolium blue chloride

Chemical. CAS 298-83-9. Formula C40H30Cl2N10O6. MW 817.2. Synthetic. NADPH-diaphorase substrate that competitively inhibits NOS nitric oxide synthase. Well-known scavenger of superoxide anions. Dye that is used for detection of alkaline phosphatase in combination with 5-bromo-4-chloro-3-indoxyl phosphate BCIP. This substrate system produces an insoluble NBT diformazan end product that is blue in color and can be observed visually. When used with BCIP, it is suitable for detection of alkaline phosphatase in western blots, for immunohistological staining procedures and for colorimetric indication of bacterial infection in blood samples. Used as a redox indicator for enzymatic reactions including dehydrogenases, threonine deaminase, glucose-6-phosphate dehydrogenase, phosphofructokinase on polyacrylamide gels, oxidases on polyacrylamide gels and pentose shunt dehydrogenses. The NBT/BCIP reaction is also used for colorimetric/spectrophotometric activity assays of oxidoreductases.

AdipoGen Phenol red sodium salt

Chemical. CAS 34487-61-1. Formula C19H13O5S . Na. MW 376.36. Synthetic Water soluble pH indicator used in the 6.8 yellow to 8.2 red range and frequently used in cell biology laboratories. Widely used as cell tissue culture pH marker. A small amount of phenol red added to the growth medium will have a pink-red color under normal conditions. Typically, 15 mg/l are used for cell culture. In the event of problems, waste products produced by dying cells or overgrowth of contaminants will cause a change in pH, leading to a change in indicator color. For example, a culture of relatively slowly dividing mammalian cells can be quickly overgrown by bacterial contamination. This usually results in an acidification of the medium, turning it yellow. The waste products produced by the mammalian cells themselves will slowly decrease the pH, gradually turning the solution orange and then yellow.

Sigma Aldrich Fine Chemicals Biosciences BioTracker 555 Orange Cyto

Lipophilic carbocyanine dyes are widely used for labeling neurons in tissues by retrograde labeling and to label membranes in a wide variety of cell types. The dyes are weakly fluorescent in aqueous phase but become highly fluorescent in lipid bilayers. Staining is highly stable with low toxicity and very little dye transfer in between cells making the dyes suitable for long-term cell labeling and tracking studies. When live cells are stained the dyes label plasma membranes and also are taken up into endocytic compartments. Cells can be fixed either before or after staining although permeabilization affects the staining pattern.Unlike PKH dyes BioTracker Cytoplasmic Membrane Dyes do not require a complicated hypoosmotic labeling protocol. They are ready-to-use dye delivery SOLUTIONons that can be added directly to normal culture media to label suspended or adherent cells in culture. Spectral PropertiesAbsorbance 549nmEmission 565nm
