Problems with mtt assay
Webb6 juni 2024 · Reduction of MTT by ascorbic acid has been previously reported by Chakrabarti et al. ( 15 ), as has the observation that some constituent of serum influenced the tetrazolium assays. The identity of the responsible serum constituent, however, was not explored in their study. Webb20 feb. 2015 · The high background absorbance values obtained from the MTT assay at the lowest seeding densities after 24 hours suggest that this assay is less sensitive at cell numbers below 1000 cells/well. The RES and SRB assays were able to detect differences in cell number as low as 500 cells/well accurately.

MTT (Sigma-Aldrich) was then added to media for 4 h, and media were discarded. DMSO (Sigma-Aldrich) was added and absorbance (560 nm) was determined using a microplate reader (Infinite M200 PRO).
WebbOriginally, the MTT assay was devised for use in eukaryotic cells lines and later applied for bacteria and fungi. As the mechanism of MTT reduction was studied in detail mostly considering eukaryotic cells, the lack of information resulted in generating a vast variety of MTT based protocols for bacterial enzymatic activity evaluation. WebbThereby, the reduction reaction of MTT relies on the cellular metabolic activity of NADPH flux. The cells like thymocytes and spherocytes have low metabolic activity rates, due to …
1. Inoculate cells into 96-well plate at 2,500-5,000 cells/well in 100 µL volume. Incubate overnight at 37°C with 5% CO2 to allow cell adhesion. 2. Add MTT [3-(4,5-dimethylthiazolyl-2)-2,5 diphenyltetrazolium bromide] solution (10 µL) to each well and incubate for 3 h at 37°C with 5% CO2. 3.
