apoptosis — Svenska översättning - TechDico
Detection can be analyzed by flow cytometry or by fluorescence microscopy. The kit can differentiate apoptosis and necrosis when performing both Annexin V-FITC and PI staining. Successful detection of early apoptosis with Annexin V-FITC is dependent upon several factors including cell type and level of membrane PS, amount of PS that is exposed during apoptosis, method (or agent) inducing apoptosis, time of apoptotic induction, as well as degree of mechanical manipulation. Annexin V luciferase fusion proteins supplied in the assay reagent bind to PS during early apoptosis and are detected with a simple luminescence signal. The assay reagent also includes a DNA-binding dye, which enters the cell and generates a fluorescent signal upon loss of membrane integrity. Numerous DNA binding viability dyes can be used in the annexin V assay including PI, DAPI and DRAQ7 . The Millipore Muse mini flow cytometer can be used to determine apoptosis levels in a cell sample by labelling with annexin V-PE and 7-AAD as the viability dye, see figure.
Detection of Apoptosis using Annexin V and NC-3000™. Translocation of phosphatidylserine (PS) from the inner to the outer membrane layer happens early in apoptosis and can be detected with Annexin V coupled to a fluorochrome. Request a Quote. Annexin V-FITC staining of apoptosis in Jurkat T cells. Annexin V-FITC staining of Annexin V (or Annexin A5) is a member of the annexin family of intracellular proteins that Annexin V may be conjugated to fluorochromes including Phycoerythrin (PE). This format retains its high affinity for PS and thus serves as a sensitive probe for flow cytometric analysis of cells that are undergoing apoptosis.
All annexin family members share the same characteristic of Ca 2+-dependent binding to negatively charged phospholipid surfaces (1).During early apoptosis, phosphatidylserine (PS) is translocated from the cytosolic side of the plasma membrane to the cellular surface. Detection of apoptosis of PCV2-infected PIECs by flow cytometry Cell apoptosis assay was carried out in accordance with the previously reported method [ ]. as follows: Apoptosis of PCV2-infected PIECs was detected with the Annexin V-FITC apoptosis detection kit (Beyotime Institute of Biotechnology, Beijing, China) according to the manufacturer’s instructions.

The ApoAlert Annexin V-FITC Apoptosis Kit provides a simple and effective method to detect one of the earliest events in apoptosis—the externalization of phosphatidylserine (PS)—in living cells. Soon after apoptosis is induced, PS is translocated from the inner leaflet of the plasma membrane to the outer leaflet. Using fluorescently labeled Annexin V the externalization of PS can easily be detected. Annexin V may also bind to PS on late apoptotic and necrotic cells but as the membrane integrity on these cells has been lost, these cells can be distinguished from early apoptotic cells by the use of the impermeant dye propidium iodide. In early-stage apoptosis, the plasma membrane excludes viability dyes such as propidium iodide (PI), 7-AAD, or Fixable Viability Dyes such as eFluor™ 660 or eFluor™ 780.

Model of plasma membrane; Apoptosis induction by UV-irradiation Background. Annexin V belongs to the annexin family of proteins consisting of over 160 members. All annexin family members share the same characteristic of Ca 2+-dependent binding to negatively charged phospholipid surfaces (1).During early apoptosis, phosphatidylserine (PS) is translocated from the cytosolic side of the plasma membrane to the cellular surface.
Suitable for flow cytometry; Annexin V-FITC kit allows fluorescent detection of annexin V bound to apoptotic cells and quantitative determination by flow cytometry; Detects apoptosis earlier in the process than DNA-based assays such as TUNEL; ADVANCED SEARCH.
