After treatment, human colon cancer cell line with HCT-116 WT, p53−/− (HCT-116 p53-KO), DLD1 and Bax−/− (HCT116 Bax-KO) were suspended in 1 × 105 cells/ml, and 5 μl Annexin V and 5 μl propidium iodide staining solution were added to 100 μl of the cell suspension. Then added 400 μl Binding Buffer to the cell suspension again. After the cells were incubated at room temperature for 10 min in the dark, stained cells were assayed and quantified using a FACSort Flow Cytometer (Beckman Coulter, Brea, CA, USA). Cell debris was excluded from the analysis by an appropriate forward light scatter threshold setting. Compensation was used wherever necessary.

Apoptosis Assay of Colon Cancer Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
For flow cytometry analysis (FACS analysis), human colon cancer cell lines with HCT116, RKO, SW48 were harvested in 1 × 105 cells/mL after using different treatment. These groups were suspended by 100 μL binding buffer, and 5 μL Annexin V and 5 μL propidium iodide staining solution were added to the cell suspension respectively. Later, added 400 μL binding buffer into the cell suspension again. At room temperature, the cells were incubated in the dark for 10 min, and then cells were assayed and quantified using a FACSort Flow Cytometer (Beckman Coulter, Brea, CA, USA) at 488 nm. Fluorescent emission of FITC was measured at 515–545 nm and that of DNA-PI complexes at 564–606 nm. Cell debris was excluded from the analysis by an appropriate forward light scatter threshold setting. Compensation was used wherever necessary.

Cell apoptosis assay by Annexin V-FITC (fluorescein isothiocyanate)/propidium iodide (PI) staining The CMs apoptosis was measured using Annexin V-FITC Apoptosis Detection Kit (Invitrogen Corporation), as our established method21 . Briefly, cultured cells (at a density of 3 × 105 /ml) were washed twice with PBS and incubated in 500 μl binding buffer containing 5 μl of Annexin V-FITC and 5 μl of PI in the dark for 15 min at room temperature. The stained samples were then analyzed on a FACSort flow cytometer within an hour following the manufacturer’s protocol (Beckman Coulter, Fullerton, USA).

Peritoneal Macrophage Phenotyping by Flow Cytometry

Check if the same lab product or an alternative is used in the 5 most similar protocols
To identify and measure the proportion of peritoneal cell types, markers on peritoneal macrophages from patients with CAPD were measured by triple colour flow cytometry using a FACSort flow cytometer (Beckman Coulter, Inc.). Anti-CD14 (clone M5E2; cat. no. 550787; 1:100; BD Biosciences), anti-CCr7 (clone 3D12; cat. no. 552176; 1:50; BD Biosciences) and anti-CD206 (clone 19.2; cat. no. 551135; 1:50; BD Biosciences) antibodies were labelled with PerCP, PE, and FITC, respectively. Class-matched isotype immunoglobulin PerCP, PE and FITC-conjugated negative control monoclonal antibodies were added to individual tubes for all samples to identify nonspecific binding. The broad macrophage gate was refined by plotting side scatter against CD14. In patients with CAPD, CD14- and CCr7-positive cells were considered M1 macrophages, and CD14- and CD206-positive cells were considered M2 macrophages. Murine macrophages (J774A.1 cells) cultured in different concentrations of glucose were considered M1 or M2 cells based on the expression of CCr7 or CD206, respectively. The flow cytometry data were analysing using WinMDI software (version 2.9; The Scripps Research Institute).

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.
