What is the appropriate wavelength for MTT assay?
This may not be appropriate for most applications of MTT assay and you may be far beyond assay linearity. Concerning reference wavelength: 650 nm and higher are safe. Absorbance of formazan is rather low at 650 nm and you can verify it yourself: try 650 nm, 690 nm and compare (the difference will be small).

Difference Between MTT and MTS Assay - Pediaa.Com
MTT assay refers to a colorimetric assay for assessing cell metabolic activity while MTS assay refers to 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. Thus, this is the main difference between MTT and MTS assay.

ATCC - 630nm - 690nm reference absorbance readings for MTT
The reference absorbance at greater than 650 nm in the MTT assay and at 630 nm - 690 nm in the XTT assay is used to correct for nonspecific background values. Nonspecific readings include well plate variability, fingerprints etc. If the reader is capable of a measuring the absorbance at 630 nm to 690 nm, it is recommended that you take this reading.

TACS MTT Assays
MTT is reduced by metabolically active cells to insoluble purple formazan dye crystals. Detergent is then added to the wells, solubilizing the crystals so the absorbance can be read using a spectrophotometer. Samples are read directly in the wells. The optimal wavelength for absorbance is 570 nm, but any filter that absorbs between 550 and 600 nm may be

MTT Cell Viability Assay Kit - Life Technologies India
The MTT assay is based on the cleavage of the yellow tetrazolium salt MTT to purple formazan crystal by metabolic active cells (2-4). The formazan is then solubilized, and the concentration determined by optical density at 570 nm. The result is a sensitive assay with a colorimetric signal proportional to the cell number.

Low absorbance in mtt assay? - ResearchGate
All Answers ( 6) What wavelength are you using for absorbance? MTT absorbs 550-600nm but if it is possible you should optimize wavelength. I usually add 0.5 mg/mL MTT in 200uL media, incubate 3h, remove 155uL, then add 90uL DMSO, warm for 10min and resuspend to ensure it is solubilized.
