Cell counting kit 8 kit

Manufactured by Vazyme
Sourced in China

The Cell Counting Kit-8 is a colorimetric assay for the determination of viable cell number. The kit utilizes the highly water-soluble tetrazolium salt WST-8, which is reduced by dehydrogenases in viable cells to produce a yellow-colored formazan dye. The amount of the formazan dye generated is directly proportional to the number of living cells in the culture.

Cell Proliferation and Apoptosis Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
The cell proliferation assay was performed using a Cell Counting Kit-8 kit (Vazyme Biotech, Nanjing) according to the manufacturer's instructions. The absorbance at 450nm was recorded and analyzed. For cell apoptosis assay, the indicated cells were stained with Annexin V-FITC/PI cell apoptosis detection kit (BD Pharmingen, San Diego, CA, USA) and were analyzed with a flow cytometer (BD FACSCalibur, San Jose, CA, USA)

BMSC Viability Assay with OPC

Check if the same lab product or an alternative is used in the 5 most similar protocols
BMSCs were seeded into 96-well plates (the cell density at 5 × 103 per well). BMSCs were incubated with different concentration of OPC (0, 2.5, 5, 10, 20, 40, and 80 µmol/L) for 24h, or were incubated with 10 µmol/L OPC for different times (0, 6, 12, 24, and 48 h). Cell viability of BMSCs was measured using a Cell Counting Kit-8 kit (Nanjing Vazyme Biotech Co., Ltd., Nanjing, Jiangsu, China) according to the correspondingly manufacturers’ instructions.

Antiproliferative Effects of Avasimibe and Fatostatin in Gastric Cancer

Check if the same lab product or an alternative is used in the 5 most similar protocols
The antiproliferative effect of avasimibe and fatostatin (MedChemExpress, Shanghai, China) was evaluated with a Cell Counting Kit-8 kit (CCK-8, Vazyme, Nanjing, China). One day before avasimibe treatment, GC cells were seeded in 96-well plates (5,000 cells/well). The cells were treated with avasimibe for 24 h or 48 h. After the indicated time, 10 µL per well of CCK-8 solution was added and incubated at 37°C for 1 h. Absorbance was recorded at 450 nm, and five independent assays were carried out.
For the plate colony formation assay, GC cells were seeded in 6-well plates or 12-well plates (1,000 cells/well in 6-well plates and 500 cells/well in 12-well plates) and incubated for 10–14 days. The medium with or without avasimibe was changed every other day. Then, the cells were fixed with 4% paraformaldehyde for 15 min and stained with crystal violet for 1 h. Images were acquired with a digital camera, and three independent assays were carried out.

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.
