Celltilter 96 aqueous one solution cell proliferation assay

Manufactured by Promega
Sourced in United States

The CellTiter 96® Aqueous One Solution Cell Proliferation Assay is a colorimetric method for determining the number of viable cells in proliferation or cytotoxicity assays. The assay involves the use of a tetrazolium compound (MTS) that is bioreduced by cells into a colored formazan product that is soluble in tissue culture medium. The absorbance of the formazan product is directly proportional to the number of living cells in culture.

AGS cells were seeded in 96-well plates with a final volume of 200 μL of complete medium per well and grown to 50% and 100% confluence. Upon reaching the desired confluence, AGS cells were incubated with 200 nM of Cy3_ HP_ LNA/2OMe _PS diluted in hybridization buffer [0.5 M urea and 900 mM NaCl; 1% (v/v) or 5% (v/v)] or in complete medium (untreated control) for 24 hours. At the end of the incubation period, the cell viability was evaluated using CellTilter 96 Aqueous One Solution Cell Proliferation Assay (Promega Corporation, Madison, WI), according to the manufacturer’s instructions. Absorbance at 490 and 630 nm was measured using a microplate reader (Biotek Instruments Inc. Synergy MX, USA). Background absorbance values were subtracted from the absorbance values generated with MTS assay. The values from treated cells were compared with the values generated from untreated control cells and reported as percent viability. All experiments were performed in triplicate.

The human gastric epithelial cell line AGS (ATCC® CRL-1739) was cultured in RPMI medium 1640 Glutamax I (Gibco, Invitrogen, Grand Island, NY, USA) supplemented with 10% (v/v) fetal bovine serum (FBS, HyClone, Thermo Fisher Scientific, Inc, UK) and 1% (v/v) Penicillin/Streptomycin (Gibco) at 37°C in a humidified 5% CO2 atmosphere. Cells were seeded at 1.6 x 105 cells/well in a 96-well plate. After overnight, media were changed and cells were incubated with predetermined concentrations (0.4 μM to 2 μM) of Cy3_HP_ LNA/2OMe _PS probe diluted in vehicle (0.5 M urea and 900 mM NaCl) or only with the vehicle, for 24 h. Cell viability was assessed by CellTilter 96® Aqueous One Solution Cell Proliferation Assay (Promega Corporation, Madison, WI), according to the manufacturer’s instructions. Untreated cells served as a negative control. The experiments were performed in triplicate.

Proliferation Assay for 3D Cell Spheroids

Check if the same lab product or an alternative is used in the 5 most similar protocols
A total of 1.5 × 104 HCT116 cells were seeded in 96-well low attachment plates in SCM, and then newly formed spheroids were treated with BK and NT analogues in duplicate. The entire experiment was repeated three times. Non-treated cells were used as a negative control. After 3 days, cell proliferation was assessed by a colorimetric CellTilter 96® Aqueous One Solution Cell Proliferation Assay (Promega Corporation, Madison, WI, USA), according to the manufacturer’s instructions. Briefly, 20 μL of CellTiter 96® AqueousOne Solution Reagent was added into each well of the 96-well assay plate containing the samples in 200 μL of culture medium. After 4 h of incubation, the absorbance at 490 nm was recorded using a microplate reader (Epoch, BioTek Instruments, Winooski, VT, USA).
The same test was used in the preliminary experiments with adherent HT29 cells.

Cell Viability Assay Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cell viability was assessed by using the CellTilter 96 Aqueous One Solution Cell Proliferation Assay (Promega Corporation, Madison, WI, USA), according to the manufacturer’s instructions. Cells were seeded at a density of 1 × 104 cells/well into 96-well plates. After their subjection to different treatments, the cells were incubated with 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H–tetrazolium, inner salt (MTS) solution at a final concentration of 0.4 mg/ml for 4 h at 37 °C. One Solution Reagent was then added directly to the culture wells, and the plates were incubated for 4 h, following which the absorbance at 490 nm was recorded with a 96-well plate reader [17 (link), 18 (link)]. The absorbance was measured at 490 nm with a Multiskan GO microplate spectrophotometer (Thermo Fisher Scientific).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
