Annexin 5 fitc pi apoptosis detection kit

Manufactured by Abcam
Sourced in United States, United Kingdom

The Annexin V-FITC/PI Apoptosis Detection Kit is a laboratory product used to detect and quantify apoptosis in cell samples. It utilizes Annexin V conjugated to fluorescein isothiocyanate (FITC) and propidium iodide (PI) to identify and differentiate between early apoptotic, late apoptotic, and necrotic cells.

Apoptosis Detection in H1650 Cancer Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
To estimate the pathway of H1650 cancer cell death, an Annexin V-FITC/PI apoptosis
detection Kit (BioVision, Mountain View, California) was used to detect the percentage of
apoptotic H1650 cells.20 (link) Briefly, H1650 cancer cells were plated onto 6-well plate and transfected with
PS2ODNs when the cells reached 70% to 80% confluence. The mismatched sequence and
apoptosis inducer kit (Beyotime, Shanghai, China) were used as the negative and positive
controls, respectively. After incubation, the cells were harvested with 0.25% wt/vol
trypsin for apoptosis detection. Annexin V-FITC and PI were added for a 30-minute
incubation at 37°C in the dark to stain the harvested cells, followed by 2 washes with
phosphate-buffered saline. The stained cells in each group were detected by flow cytometry
(BD, New Jersey, USA) at an excitation wavelength of 488 nm and emission wavelengths of
525 and 625 nm.

Apoptotic cells were detected by an Annexin V-FITC/PI apoptosis detection kit (BioVision) according to manufacturer's instruction. MCF-7 cells and MCF-7/ADR cells were treated with different concentrations of EVO. After 48 h of incubation, cells were trypsinized and collected by centrifugation at 500 g/min for 5 min. After being washed twice with cold PBS and gently suspended in 100 µl binding buffer, cells were stained with 5 µl of Annexin-FITC and 10 µl of PI solution and incubated in the dark at room temperature for 15 min. Cell apoptosis was analyzed by a flow cytometer (BD Biosciences). All experiments were performed in triplicate.

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.
