Image Unavailable-APOSBI5837-5G

2,2'-Bicinchoninic acid disodium salt ≥98%

Leverantör: Apollo Scientific
Beskrivning: Used in the determination of protein concentration. Proteins reduce alkaline Cu(II) to Cu(I) which complexes with BCA to form a purple complex. Absorbance at 562nm is directly proportional to protein concentration.

Metylenblått (Neisser) för mikroskopi, Sigma-Aldrich®

Artikel nummer : (01363-100ML-F)
Leverantör: SIGMA ALDRICH MICROSCOPY
Beskrivning: Methylene blue, Neisser formulation. Well developed granules of volutin (polyphosphate) may be seen in unstained wet preparations as round refractive bodies within the bacterial cytoplasm. With methylene blue they stain metachromatically, a reddish purple color.

3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) ≥98%, Ultrapure

Leverantör: VWR Chemicals
Beskrivning: MTT, a yellow tetrazole dye, can be reduced to a water-insoluble purple formazan compound by mitochondrial reductase enzymes. Since reduction only occurs in living cells, the quantitation of formazan can be equated to the number of viable cells in the population.

1-Methoxy-5-methylphenazinium methyl sulphate ≥95%, Sigma-Aldrich®

Leverantör: SIGMA ALDRICH MICROSCOPY
Beskrivning: 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.

Coliform swab

Artikel nummer : (710-1479)
Leverantör: HYSERVE
Beskrivning: Easy to carry early warning test for contamination of surfaces with coliform bacteria. Based on a certified method, the Coliform Swab provides a simple method for the qualitative detection of these bacteria - with a clear colour change from purple to yellow in the presence of coliform bacteria.

Nitroblå tetrazolium ≥90%, Sigma-Aldrich®

Leverantör: SIGMA ALDRICH MICROSCOPY
Beskrivning: Nitrotetrazolium blue (NBT), in combination with BCIP (5-bromo-4-chloro-3-indolyl-phosphate), is required for the detection of labeled probes in western blots. It is part of the colorimetric detection assay. NBT and BCIP dyes detect alkaline phosphatase activity, thereby generating an insoluble purple dye (diformazan). The dye is visible at areas where the labeled probe has hybridised to its target.

Substrate for western blotting, 1-Step™ NBT/BCIP plus suppressor

Artikel nummer : (PIER34070)
Leverantör: Thermo Fisher Scientific
Beskrivning: The 1-Step NBT/BCIP plus suppressor is a one-component alkaline phosphatase substrate that inhibits endogenous phosphatase activity. This substrate reacts with calf intestinal alkaline phosphatase to produce a dark purple precipitate and is ideal for immunohistochemistry and <i>in situ</i> hybridisation applications.

Product Image-HACH2186400

Visual comparator test kit, ethylene glycol

Artikel nummer : (HACH2186400)
Leverantör: Hach
Beskrivning: Ethylene glycol (anti-freeze) contamination of automotive lubricants is an indication of a cracked engine block. Glycol presence also can indicate leaks in cooling systems. This test kit model EG-1 presents a purple colour if ethylene glycol and other 1,2 glycols are present in oil or water.

Substrate for western blotting, NBT (nitro-blue tetrazolium chloride)

Artikel nummer : (PIER34035)
Leverantör: Thermo Fisher Scientific
Beskrivning: NBT (nitro-blue tetrazolium chloride) yields a blue-purple, water-insoluble product upon reduction of the tetrazolium salt. The product of reduction is NBT-formazan. This substrate is widely used for immunochemistry applications because the color is linear and stable. NBT is used as the substrate for both glucose oxidase and alkaline phosphatase systems.

1-Step™, Pierce™ Chloronaphthol

Artikel nummer : (PIER34012)
Leverantör: Thermo Fisher Scientific
Beskrivning: Chloronaphthol (4-CN) is a peroxidase substrate used for chromogenic detection of HRP in immunoblotting and immunohistochemical applications. This product is less sensitive than other precipitating substrates, but the distinct blue to blue-purple precipitate photographs well and can be useful in double-staining applications. The coloured product is soluble in alcohol and xylenes, but is not soluble in aqueous buffers. The 1-Step Chloronaphthol is supplied ready to use.
