  • Product overview

    Monitoring cell cytotoxicity is one of the most essential tasks for studying cellular functions. There are a variety of parameters that can be used. ab112118 uses a proprietary water-soluble dye that changes its absorption spectra upon cellular reduction. The absorption ratio change is directly proportional to the number of living cells. The characteristics of its high sensitivity, non-radioactivity and no-wash method make ab112118 suitable for high throughput screening of cell proliferation or cytotoxicity against a variety of compounds.

    ab112118 does not require pre-mixing of components and has higher sensitivity compared to tetrazolium based colorimetric assays (such as MTT and XTT). It comes with reagents sufficient to run 1000 assays. The kit components are quite stable with minimal cytotoxicity, thus longer incubation times (such as 24-48 hours) are possible if required.
    ab112118 is robust and convenient to use. It can be readily adapted for a wide variety of instrument platforms. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format.

    • •HeLa: day before experiment cells seeded in 96 wp @ 1e4 cells/well and treated with 1µM, 10 µM and 50 µM Camptothecin (incubated for 24h); on the day of experiment cells incubated with Assay Solution for 2 hours.

      •NIH3T3: day before experiment cells seeded in 96 wp @ 1e4 cells/well and treated with 1µM, 10 µM and 50 µM Camptothecin (incubated for 24h); on the day of experiment cells incubated with Assay Solution for 2 hours.

    • CHO-K1 cell number response was measured with ab112118. CHO-K1 cells at 0 to 10,000 cells/well/100 µL were seeded overnight in a black wall/clear bottom 96-well plate. The cells were incubated with 20 µL/well of Assay Solution for 3 hours at 37 oC. The absorbance intensity was measured at 570 nm and 605 nm. The ratio of OD570/OD605 is proportional to the number of cells as indicated.

    Effects of dopamine of cell viability

    Excellent Good 4/5 (Ease of Use)
    Increased concentrations of dopamine reduce cell survival independently of α-synuclein presence.
    Normal SH-SY5Y cells and SH-SY5Y cells transfected with 1 µg α-synuclein siRNA were treated with varying concentrations of dopamine with and without MG-132 proteasome inhibitor for 72 h. Cell viability was measured using ab112118 cell cytotoxicity assay kit (abcam, Cambridge, UK). Data was analysed using one-way ANOVA corrected by post-hoc Sheffé's test (* p < 0.05, ** p < 0.01) and expressed as a relative percentage of survival compared to PBS vehicle control. Error bars represent ± standard deviation of four independent replicates.
