Cell Cycle and Apoptosis Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
ESCC cells were collected and digested at 48 hours after transfection. For the cell cycle analysis, the cells were fixed in 70% ethanol precooled at −20°C. On the second day, the cells were stained with propidium iodide buffer (BD Biosciences, San Jose, CA, USA) in flow cytometry (FCM) tubes to detect the cell cycle distribution. Annexin-V and 7-AAD dyes were prepared for the cell apoptosis assay. The cells were incubated in the dark for about 15 minutes. Cell apoptosis and the cell cycle distribution were examined by using a FACSCalibur flow cytometer (BD Biosciences, San Jose, CA, USA). The data were analyzed by FlowJo software.

Clonogenic Assay and Cell Migration

Check if the same lab product or an alternative is used in the 5 most similar protocols
Bladder cancer cells were seeded in the 6-well plate with 1000 cells/well. Subsequently, the plates were placed in the incubator with standard culture. Finally, clones were harvested and stained with 0.1% crystal violet (Beyotime, Shanghai, China) when over 50 cells per clone were counted. The migration and matrigel invasion assays were performed to evaluate cell migration and invasion abilities by using transwell chamber as described previously. 13 Flow cytometry assay (FCM) for cell apoptosis and cell cycle analyses Cell apoptosis were tested by staining cells with Annexin V-uorescein isothiocyanate (FITC) and propidium iodide (PI) (BD Biosciences, USA) according to the manufacturer's instructions. Flowjo VX10 software was used for analyzing the results. For cell cycle analyses, cells were harvested and stained with propidium iodide buffer (BD Biosciences, USA) according to the manufacturer's instructions. The ModFit LT software was used for analyzing the results.

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.
