Learn about your options when you need an apoptosis assay or an apoptosis marker. Get an introduction to the mechanisms of apoptosis. Our offers a wide array of cell apoptosis assays:Annexin V binding assays, Caspase activity assays,Mitochondrial membrane potential assays DNA. Cell Based Assays for Apoptosis Detection. Apoptosis, or programmed cell death, is a growth-limiting regulatory mechanism by which cells can trigger their own death in response to extracellular signals because of irreparable cellular or DNA damage. Apoptosis is a multistep process.

The Cell-Apopercentage dye binds to the externally exposed phosphatidylserine and the dye is taken up into the cell via this phosphatidylserine transmembrane movement.
The choline phospholipids make up most of the lipid in the extracellular membrane. This organisational composition is essential for the normal functions of a viable cell, including the insertion of protein receptors and transporters between the phospholipid molecules. The transfer of phosphatidylserine to the outside of the membrane permits the transport of the APOPercentage dye into the cell.
The uptake of the dye is uni-directional, leading to dye accumulation within the cell. As the cell shrinks in volume, during the apoptotic process, the cell dye content becomes more concentrated.
Apoptosis assays are widely available, each based on a different stage of the apoptotic process. In some cases apoptosis can be induced without detectable DNA degradation and caspase activity may be reduced at late stage apoptosis.
Therefore, running two different apoptosis detection methods simultaneously is recommended to confirm that cell death is occurring due to apoptosis. The Cell Apopercentage APOPTOSIS Assay can be used on its own or alongside other apoptosis detection assays, such as a caspase activity assay, a tunel assay based on DNA fragmentation or an annexin-V assay based on binding of Annexin V to phosphatidyl serine that has translocated to the outside of the cell membrane during apoptosis.
In contrast to necrotic cells, apoptotic cells are characterized morphologically by compaction of the nuclear chromatin, shrinkage of the cytoplasm and production of membrane-bound apoptotic bodies.

Several approaches have been developed to study apoptosis. Cell death cascades are complex and dynamic, underscoring the importance of a multi-parametric approach for accurate assessment Figure 1. To order Buy Cat.
We recommend that you first optimize for the tissue type that you are working with. Does GeneCopoeia have a kit that can perform apoptosis, cell cycle and cell viability assays all in one kit? Our apoptosis kits A, A, A, A contain the component PI, which could be used for cell cycle and cell viability assays.
