Water-soluble tetrazolium salts are more recent alternatives to MTT: they were developed by introducing positive or negative charges and hydroxy groups to the phenyl ring of the tetrazolium salt, or better with sulfonate groups added directly or indirectly to the phenyl ring.

The MTS assay is often described as a 'one-step' MTT assay, which offers the convenience of adding the reagent straight to the cell culture without the intermittent steps required in the MTT assay.

However this convenience makes the MTS assay susceptible to colormetric interference as the intermittent steps in the MTT assay remove traces of coloured compounds, whilst these remain in the microtitre plate in the one-step MTS assay.

Precautions are needed to ensure accuracy when using this assay and there are strong arguments for confirming MTS results using qualitative observations under a microscope.

This, however, is prudent for all colormetric assays. WSTs water-soluble tetrazolium salts are a series of other water-soluble dyes for MTT assays, developed to give different absorption spectra of the formed formazans.

Finally, WST assays 1 can be read directly unlike MTT that needs a solubilization step , 2 give a more effective signal than MTT, and 3 decrease toxicity to cells unlike cell-permeable MTT, and its insoluble formazan that accumulate inside cells.

Tetrazolium dye reduction is generally assumed to be dependent on NAD P H-dependent oxidoreductase enzymes largely in the cytosolic compartment of the cell.

Cells with a low metabolism such as thymocytes and splenocytes reduce very little MTT. In contrast, rapidly dividing cells exhibit high rates of MTT reduction.

It is important to keep in mind that assay conditions can alter metabolic activity and thus tetrazolium dye reduction without affecting cell viability.

In addition, the mechanism of reduction of tetrazolium dyes, i. From Wikipedia, the free encyclopedia. Acta Histochemica. Biotechnology Annual Review.

XTT Assay Kit ab provides an easy to use tool for use with cell cultures to study changes in the number of cells and their metabolic activity.

This provides insights into cell viability, cell proliferation, and cytotoxicity. The formazan product can be detected using an absorbance-based microplate reader.

As the reagents used in the XTT and their products are non-toxic and the assay does not involve cell lysis, the XTT assay can be used to measure multiple timepoints or for continual measurement.

One bottle of each sufficient for one 96 well plate are thawed, mixed together, added to cells, and incubated. The viability signal is detected using an absorbance-based microplate reader.

In actively respiring viable mammalian cells, the water-soluble XTT reagent is reduced and converted to an orange-colored formazan product.

In addition to being cost effective, colorimetric viability assays generate consistent results with low well-to-well variability.
