A549 cells with indicated treatment were harvested and fixed with 70% ethanol. These cells were then stained using propidium iodide (PI) and the cell cycle stage assessed by flow cytometry. To evaluate apoptosis, cells were cultured at 80% confluence and trypsinized and stained with a PI/Annexin V Apoptosis Detection Kit (Vazyme, Jiangsu Sheng, China). Data were collected and analyzed on a BD FACSC Flow Cytometer using FACSD software (BD Biosciences, San Jose, CA, USA).

Control or fucosylated NK cells and A20-luc+/yfp cells were co-cultured in 96-well plates at different effector/target (E: T) ratios. After co-cultured for 6h, apoptosis of yfp+ lymphoma cells were detected by Annexin V/PI Apoptosis Detection Kit (Vazyme, China). The cytotoxic activities of NK cells were represented by the apoptotic rates.

5 × 105 cells were seeded in 6-well plates per well overnight and treated with indicated drugs for 48 h. The collected total cells were stained with the Annexin V-PI apoptosis detection kit (Vazyme, China) and analyzed by flow cytometry (Becton Dickinson, USA). FlowJo 6.0 was used to analyze the results. Each assay was performed for three times.

An Annexin V-PI apoptosis detection kit (Vazyme Biotech Co. Ltd., China) was used in a manner similar to that of a previous description [22 (link), 23 (link)] to detect apoptosis. Thereafter, fluorescence-activated cell sorting (FACS) was utilized to count the stained cells using CellQuest software (BD Biosciences, USA) connected to a Calibur flow cytometer. A TUNEL FITC Apoptosis Detection Kit (Vazyme Biotech Co. Ltd., China) was used, as instructed by the manufacturer, to conduct TUNEL staining. Immunofluorescence was observed using a Nikon ECLIPSE E800 fluorescence microscope.

Cell apoptosis was detected using Annexin V/PI apoptosis detection Kit (Vazyme, China) according to the manufacturer's instructions. The cells were collected and washed twice after 36–48 h of treatment. Thereafter they were suspended in 400 μL of binding buffer, 10 μL of PI solution and 5 μL of Annexin V antibody conjugated with fluorescein isothiocyanate (FITC). After 15 min at 4 °C in a dark environment of incubation in the mixture, apoptosis rate was measured by flow cytometry. Apoptosis was quantified using FlowJo-V10 software (BD Biosciences, San Jose, CA, USA).

Apoptosis was analyzed using the Annexin V-PI apoptosis detection kit (A211, Vazyme Biotech Co., Ltd, Nanjing, China). Briefly, the treated BxPC-3 and PANC-1 cells were trypsinized and washed twice with ice-cold PBS and re-suspended in the binding buffer at a concentration of 105 per well in a total volume of 100μl. Then, the cells were supplied with 5 μl of Annexin V-FITC and 5 μl of PI and incubated in dark at room temperature for 10 min. After that, 200 μl of binding buffer was added into each sample for flow cytometry analysis.

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.
