Annexin 5 propidium iodide staining kit

Manufactured by Thermo Fisher Scientific
Sourced in Austria

The Annexin V/propidium iodide (PI) staining kit is a laboratory reagent used for the detection and quantification of apoptotic and necrotic cells. It contains Annexin V, which binds to phosphatidylserine, and propidium iodide, which stains DNA. The kit allows for the identification of different cell populations based on their staining patterns.

After 72h of treatment of cells with cetuximab and/or celecoxib (6-well plates, 3 × 106 cells/well) the fraction of apoptotic cells was estimated by using an Annexin-V/propidium iodide (PI) staining kit (Bender MedSystems, Viena, Austria), according to manufacturer´s recommendations. Binding of fluorescein-conjugated Annexin-V and PI was measured by flow cytomewtry (FACSCalibur; BD, Franklin Lakes, NJ, USA) to quantify the percentage of apoptotic cells.

Quantification of Apoptosis by Annexin-V/PI Flow Cytometry

Check if the same lab product or an alternative is used in the 5 most similar protocols
The fraction of apoptotic cells was estimated after 48h of treatment of cells growing in the absence or in the presence of EGF (100 ng/mL) with different doses of AEE788 and/or celecoxib in 6-well plates at a density of 3 × 106 cells/well. Viability was assessed by using an Annexin-V/propidium iodide (PI) staining kit (Bender MedSystems, Vienna, Austria), according to manufacturer´s recommendations. Binding of fluorescein-conjugated Annexin-V and PI was measured by flow cytometry (FACSCalibur; BD, Franklin Lakes, NJ, USA) to quantify the percentage of apoptotic cells.

Cell cycle analysis and apoptotic cell quantification were performed using the Guava cell cycle reagent (Millipore Sigma) or the annexin V/propidium iodide (PI) staining kit (Thermo Fisher Scientific), respectively, according to the manufacturer's instructions. Cells were quantified on a BD LSR II flow cytometer and analyzed using FlowJo software (FlowJo).
Cell proliferation was measured using the MTT reagent and cells cultured in 96-well plates. Cells were incubated with MTT for 4 h at 37 °C. After incubation, culture media was removed and 150 μl of DMSO was added in order to solubilize the MTT formazan crystals. Optical density was determined at 590 nm using a TECAN plate reader. At least three independent experiments were performed.

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.
