Fitc annexin 5 detection kit 1

Manufactured by BD
Sourced in United States

The FITC Annexin V Detection Kit is a laboratory reagent used to detect and quantify apoptotic cells. It contains Annexin V, a protein that binds to phosphatidylserine, and fluorescein isothiocyanate (FITC) for fluorescent labeling. The kit provides a tool for researchers to analyze and study cellular apoptosis processes.

BD Annexin V: FITC Detection kit I (BD Pharmingen) was used according to the
manufacturer’s instructions. Briefly, lineage-depleted BM cells were stained with
HSC-defining antibodies before washed and incubated with camptothecin at a final
concentration of 5 μM for 5 hours at 37°C. The samples were then washed with
ice-cold FACS buffer and resuspended in 1X Annexin binding buffer, to which Annexin V and
PI were added. The samples were vortexed and incubated in the dark for 15 minutes at room
temperature. Additional Annexin binding buffer was then added after which the samples were
analyzed within one hour.

Cells were incubated at 5 × 105 cells/mL with (1.25, 2.5, 5.0, and 10 μM) or without ONC201 treatment for 48, 72 or 96 hrs, and then harvested. The apoptotic cells were analyzed by flow cytometry using the Annexin V-FITC Detection Kit I (BD Pharmingen, San Diego, CA) as previously described [33 (link)].

5-8F cells and HNE2 cells were pretreated for half an hour with vehicle or 2 μM afatinib before irradiation (4Gy) and were incubated for 48 hours. Next, the apoptotic cells were analysed via flow cytometry using the Annexin V-FITC Detection Kit I (BD Pharmingen, San Diego, CA) according to the manufacturer's instructions. Flow cytometry data were plotted and analysed via the fluorescence activated cell-sorting (FACS-Vantage) system using the Cell quest software (Becton-Dickinson, San Jose, CA) within 1 hour of staining. The percentages of differently labelled cells were calculated using the FlowJo software (Tree Star).

For the proliferation assay, 20.000 cells were plated in triplicate in 24-well plates and cultured at 37°C. At the indicated time point the cells were collected and counted by trypan blue exclusion. The Annexin V-PI assay (apoptosis assay) was performed according to the manufacturer's instructions using the Annexin V-FITC detection kit I (BD Biosciences). Cell pellets were resuspended in 100 μl of binding buffer and incubated with 5 μl of FITC-conjugated Annexin-V and 5 μl of PI for 15 min at room temperature in the dark. 400 μl of 1 × binding buffer was added and the samples were immediately analyzed by flow cytometry. Samples were run on a Canto II flow cytometer (BD) and analyzed by FlowJo software, gating on live cells.

Annexin V-FITC Detection Kit I (BD Bioscience) was used to identify the distribution of early or late apoptosis induced by PBEA towards HeLa cells. The assay was conducted as instructed in manufacture's manual. The cells were later incubated with the IC 50 concentration of PBEA for 24 h, 48 h, and 72 h at 37 C with 5% CO 2. After that, the cells were washed two times with cold PBS and stained with 5 ml of FITC Annexin V and 5 ml of propium iodide (PI) for 15 min at room temperature under dark condition. Results for the stained cells were obtained (10,000 events per sample) through FACSCANTO II (BD Bioscience). The data acquired were analyzed by using FlowJo_V10 software. The test was repeated thrice independently.

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.
