Wst 1 cell viability assay kit

Manufactured by Roche
Sourced in United States, Germany

The WST-1 cell viability assay kit is a colorimetric assay that measures the metabolic activity of cells. The assay is based on the cleavage of the tetrazolium salt WST-1 by mitochondrial dehydrogenases in viable cells, resulting in the formation of a colored formazan dye that can be measured spectrophotometrically.

Cytotoxicity assay was carried out using WST-1 cell viability assay kit (Roche Molecular Biochemicals, Indianapolis, IN, USA) as per the manufacturer’s instructions. Cells were plated in triplicate in 96-well plates at the density of 2.0 × 104 cells/well in CS-C medium. Following overnight culture, the cells were incubated with the indicated concentrations of SWCNT for 24 and 72 h. After incubation, WST-1 reagent was added and the cells were incubated for an additional 4 h. The plates were then read at the wavelength of 420 nm using a microplate reader (Model 3550; BioRad, Richmond, CA, USA).

Betulinic acid was purchased form Sigma Aldrich (St Louis, MO, USA). The stock solution was prepared by diluting with DMSO (dimethyl sulfoxide) to nal concentration of 100 µM and stored at -20 o C until being used. Cell lines and all cell culture reagents were purchased from ATCC (American Type Culture Collection). WST-1 cell viability assay kit was obtained from Roche Life Science (Mannheim, Germany).
RNA isolation and cDNA synthesis kits were purchased from Thermo sher Scienti c (Massachusetts, USA). SNAIL-1 and Syndecan-2 ELISA kits were purchased form Abbkine Scienti c (California, USA). Migration and Invasion assay kits were bought from Trevigen Inc. (Gaithersburg, Maryland, USA).
Cell Lines and Cell Culture CAKI-2 (clear cell renal cell carcinoma) and ACHN (metastatic renal adenocarcinoma) cells were cultured in McCoy's 5A medium and EMEM (Eagle's Minimum Essential Medium), respectively. The cell culture media are supplemented with %1 Penicillin-Streptomycin and %10 Fetal Bovine Serum (FBS). All cell lines were maintained in humidi ed incubator with 5% CO 2 at 37°C.

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.
