Reddit Abstract We show here the identity of Alamar Blue as resazurin. Resazurin blue ADI PV-5517 nonfluorescent is reduced to resorufin pink and highly fluorescent which is further reduced to hydroresorufin uncoloured and nonfluorescent.
It is still not known how this reduction occurs, intracellularly via enzyme activity or in the medium as a chemical reaction, although the reduced fluorescent form of Alamar Blue was found in the cytoplasm and of living cells nucleus of ADI PV-5517 cells. Recently, the dye has gained popularity as a very simple and versatile way of measuring cell proliferation and cytotoxicity. This ADI PV-5517 presents numerous advantages over other cytotoxicity or proliferation tests but we observed several drawbacks to the routine use of Alamar Blue.
Tests with several toxicants in different cell lines and rat primary hepatocytes have shown accumulation of the fluorescent product of Alamar Blue in the medium which could lead to an overestimation of cell population. Also, the extensive reduction of Alamar Blue by metabolically active cells led to a final nonfluorescent product, and hence an underestimation of cellular activity. Obviously, it should not interfere with the ADI PV-5517 to be tested.
Moreover, if the same method is applicable to high throughput screening techniques and the cells can be used for further experiments, then biologists have the perfect tools. Sincea new dye fulfilling this description ADI PV-5517 been available, Alamar Blue AB [ 1 ADI PV-5517. However, greater sensitivity is achieved using the fluorescent property. This can be done either as an endpoint reading or in a kinetic fashion, providing an excellent estimation of cell proliferation, as well as the potency of toxicants.

As few as 80 cells give a reproducible and sensitive signal, which is in the range of ADI PV-5517 methods, but without all the exposure and waste disposal issues. This allows precious cells ADI PV-5517 be reused for further investigations, saving time and money, especially in the case of primary tissue cultures.
The oxidized, blue, nonfluorescent Alamar Blue is reduced to a pink fluorescent dye in the medium by cell activity likely to be ADI PV-5517 oxygen consumption through metabolism. Although it has been arbitrarily postulated as being reduced by mitochondrial enzymes [ 2 ], it is not known whether this occurs intracellularly, at the plasma membrane surface or just in the medium as a chemical ADI PV-5517. Resazurin seems to be the original name for Alamar Blue, before it had been used for ADI PV-5517 vitro mammalian cell proliferation.
It has been assessed several times on different types of cell for its cytotoxicity reliability, i. Although it compares favourably with many other cell proliferation techniques, we have uncovered some pitfalls to avoid and have also explored its mechanism of action. All ADI PV-5517 reagents and chemicals, including resazurin, were obtained from Sigma. ADI PV-5517

A DU spectrophotometer Beckman was used to measure the absorbance of Alamar Blue, resazurin and resorufin. The cartridge was conditioned by the sequential application of methanol 5 mL and water 5 mLfollowed by 10 mL of reagent. The cartridge was then washed with a further 5 mL of water and the dye, which was retained ADI PV-5517 under these conditions, was then recovered by elution with methanol 10 mL. The methanol was then removed using a ADI PV-5517 of nitrogen gas at ambient temperature prior to ADI PV-5517 analysis.
Typically, scans were collected into 65 data points over a spctral width of Hz. The extracted sample was then redissolved in D2O Livers were perfused following the method of Seglen ADI PV-5517 10 ].
Following collection, cells were checked ADI PV-5517 viability using Trypan Blue and seeded at a density of 1. Cells ADI PV-5517 harvested by trypsinization and an assessment made of their density, via haemocytometer and viability by Trypan Blue. Cells were diluted in medium to a density of 7.

Cells were treated the following day. MTT was used to assess the viability of cells following treatment. The absorbence was read on the plate reader at and nm. A subtraction analysis of the dual wavelength was performed D ADI PV-5517 D to increase accuracy of the measurement.
