Check if the same lab product or an alternative is used in the 5 most similar protocols
PC3 cells were treated with 0.1% DMSO (control) and CTN06 at the indicated concentrations for 24 h. Cell-cycle arrest was determined by the incorporation of propidium iodide (Sigma-Aldrich) into permeabilized cells. Cells undergoing apoptosis were identified using an Annexin V-FITC kit (Abcam), following the manufacturer's instructions. The cells were analyzed using a Coulter Epics XL flow cytometer (Beckman Coulter, Miami, FL, USA).

Cell cycle analysis was performed by flow cytometry. Cells were harvested with trypsinization together with floating non-viable cells. The cells were washed once with PBS and suspended in sodium citrate buffer (40 mM Na-Citrate, 0.3% Triton X-100, 0.05 mg/ml propidium iodide, PBS) 20 minutes prior to analysis. Cell cycle analysis was performed using FACSCalibur (Becton Dickinson, CA, USA) and CellQuest Pro software (Becton Dickinson). Cell cycle and apoptosis analyses were performed with ModFit LT (Verity Software House, Inc., Topsham, ME, USA) and Flowing Software ver. 2.5 (Mr. Perttu Terho, Turku Centre for Biotechnology, Finland, www.flowingsoftware.com), respectively. To further analyze the apoptosis induction after MX and MX + imatinib treatment HeLa cells were grown on 6-well plates and treated with indicated drugs for 24 and 48 hours. Medium and cells were collected and the samples were stained with Annexin-V-FITC kit (ab14085; Abcam, Cambridge, UK) according to manufacturer's instructions. Data were acquired with a FACSCalibur flow cytometer, and analyzed with Flowing Software.

Annexin V Flow Cytometry Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
Annexin V assays were performed using an Annexin V/FITC kit from Abcam (ab14085) following the manufacturer's instructions. Briefly, cells were collected and counted. Then, 1 × 105 cells were mixed with 500 μl Annexin V binding buffer, 5 μl Annexin V-FITC and 5 μl propidium iodide. The mixture was incubated for 5 mins at room temperature in the dark. The Annexin V-FITC signal was then analysed via flow cytometry (Ex=488 nm, Em=530 nm) using a FITC signal detector and a phycoerythrin emission signal detector to detect PI staining.

Endometrial Cancer Cell Line Cultivation

Check if the same lab product or an alternative is used in the 5 most similar protocols
The endometrial cancer cell lines, ECC-1 and Ishikawa, were used. The ECC-1 cell line was maintained in RPMI 1640 supplemented with 5% FBS, 300mM L-glutamine, 5 μg/ml bovine insulin, 10,000 U/ml penicillin and 10,000 μg/ml streptomycin. Ishikawa cells were grown in MEM supplemented 5% FBS, 300 mM L-glutamine, 10,000 U/ml penicillin and 10,000 μg /ml streptomycin. Both the cell lines were cultured at 37°C in a humidified atmosphere with 5% CO2. MTT (3-(,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and RNase A were purchased from Sigma (St. Louis, MO). The anti-MMPs and anti-α-tubulin antibodies were purchased from Cell Signaling (Beverly, MA). The anti-hTERT antibody and Annexin V FITC kit were purchased from Abcam (Cambridge, MA). The Enhanced chemiluminescence Western blotting detection reagents were purchased from GE Health care (GE Healthcare Life Sciences, Piscataway, NJ).

After 12 h of OGD, FFA treated AML-12 cells were washed with cold PBS twice and were trypsinized. The cells were resuspended in 500 µL of 1× binding buffer (Annexin V- FITC kit Cat# ab14085, Abcam, Cambridge, MA, USA), followed by addition of five µL of Annexin V-FITC and five µL of Propidium iodide (PI) and incubated for 15 min in the dark at room temperature. The samples were analysed using flow cytometry (Fortessa X-20, BD Biosciences, San Jose, CA, USA) and results were analysed using FlowJo (Version 10.6.1, Becton, Dickinson and Company, Franklin Lakes, NJ, USA).

RT-4 and ARPE-19 cells were grown on round coverslips placed in 12-well plates and allowed to adhere for 16 h. The cells were incubated for 48 h either untreated or with chemotherapeutic agents with or without proTAME. The cell culture media was carefully removed, and the cells were washed three times with cold PBS. Annexin V-FITC Kit (Abcam, cat no: ab14085) was used to stain the cells according to the manufacturer’s protocol. A camera (DFC425, Leica) attached fluorescence microscope (Leica LM 4000B) was then used to examine the cells.

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.
