Annexin V, belonging to a recently discovered family of proteins, the annexins, with anticoagulant properties has proven to be a useful tool in detecting apoptotic cells since it preferentially binds to negatively charged phospholipids like PS in the presence of Ca 2+ and shows minimal binding to phosphatidylcholine and sphingomyeline. Annexins are group of cellular proteins that bind to phospholipids in a calcium-dependent manner. A member of this group, Annexin V, has proven to be a useful tool in detecting apoptotic cells since it has a high affinity for PS. Annexin V:FITC Assay Kit used for cell cycle analysis of cells treated with Arsenic trioxide and Macuna macrocarpa extract by flow cytometry. Image caption: Annexin V-FITC/propidium iodide (PI) analyses of arsenic trioxide (ATO)- and/or crude methanolic extract of Mucuna macrocarpa (CMEMM)-treated cells. Annexin 5 has also been described as placental anticoagulant protein I, vascular anticoagulant-alpha, endonexin II, lipocortin V, placental protein 4 and anchorin CII. The gene spans 29 kb containing 13 exons, and encodes a single transcript of approximately 1.6 kb … Annexin V belongs to the annexin family of intracellular proteins that bind to membrane phospholipids in a calcium-dependent manner. This dye has a high affinity for phosphatidylserine (PS) that is present in the inner leaflet of the plasma membrane. During early-stage cell apoptosis, PS is translocated from the inner to the outer leaflet of The use of the annexin V apoptosis assay protocol is a common method for detecting apoptotic cells.

Annexin V (or Annexin A5) is a member of the annexin family of intracellular proteins that binds to phosphatidylserine (PS) in a calcium-dependent manner. PS is normally only found on the intracellular leaflet of the plasma membrane in healthy cells, but during early apoptosis, membrane asymmetry is lost and PS translocates to the Annexin V has a strong, Ca 2 +-dependent affinity for PS and therefore can be used as a probe for detecting apoptosis. Save time with a validated Annexin V assay kit/reagent For robust results, we recommend our range of one-step Annexin V staining/detection kits and reagents for use in flow cytometry and cell imaging.

Annexin V was found to play a major role in matrix vesicle-initiated cartilage calcification as a collage-regulated calcium channel. Annexin V binds to procoagulant phospholipids (Vascular anticoagulant alpha) with high affinity. Annexin V’s preferential binding partner is phosphatidylserine (PS). PS is predominantly located in membrane leaflets,

Annexin V-FITC apoptosis detection kit. Easy, quick assay to distinguish apoptotic cells vs necrotic cells

Paul Meers; and; Tanya APC Annexin V Apoptosis Detection Kit with PI has been specifically designed for the identification of apoptotic and necrotic cells.Annexin V (or Annexin A5) is a Sep 2, 2019 Annexin V is a 35 kDa phospholipid-binding protein. Its strong calcium- dependent affinity for phosphatidylserine (PS) can be used to identify Therefore, annexin V-binding, in conjunction with flow cytometry, was used to evaluate the integrity of the sperm plasma membrane after different cryostorage Annexin V. Annexins are a family of caclium-dependent phospholipid-binding proteins.

Annexin A-V is the major player when it comes to mechanisms of coagulation. Like other annexin types, annexin A-V can also be expressed on the cell surface and can function to form 2-dimensional crystals to protect the lipids of the cell membrane from involvement in coagulation mechanisms.

Engelsk definition. A protein of the annexin family isolated from human PLACENTA and other tissues. Annexin V is one of few proteins that bind heparin in a calcium-dependent manner (78) as verified by X-ray crystallography (79). The interaction of annexin V with heparin involves an oligosaccharide sequence of 6–8 residues (78) and sulfate groups on heparin are important. This 'inhibitory' effect of annexin V is apparently allosteric and saturates at about [ANT]sat = 4 microM annexin V for vesicles of a = 100 nm at 1 mM total lipid concentration, 0.13 mM total Ca2+ concentration and at T = 293 K. Data analysis in terms of Gibbs area-difference-elasticity energy suggests that the bound annexin V reduces the gradient of the lateral pressure across the membrane. We describe a rapid and reliable method to quantitate the extent of apoptosis in neuronal cell cultures.

Annexin V protein demonstrates high affinity, specificity, and sensitivity for PS and can be used as a marker of early apoptosis. In order to rule out "leaky" necrotic cells, annexin V must be used in tandem with reagents that determine the integrity of the cell membrane, such as propidium iodide (2).

Analyze annexin V-FITC binding by flow cytometry (Ex = 488 nm; Em = 350 nm) using FITC signal detector (usually FL1) and PI staining by the phycoerythrin emission signal detector (usually FL2). For adherent cells, gently trypsinize and wash cells once with serum-containing media before incubation with annexin V-FITC (Steps A. 3–5). Annexin V, a 36-kDa calcium-binding protein, binds to PS; therefore, fluorescently labeled Annexin V can be used to detect PS that is exposed on the outside of apoptotic cells. Annexin V can also stain necrotic cells because these cells have ruptured membranes that permit Annexin V to access the entire plasma membrane. Annexin’s drug candidate ANXV is a recombinant human Annexin A5. It is in development for intravenous administration in patients with acute vascular diseases, where ANXV is expected to improve the body’s own ability to protect and repair blood vessels. Annexin A5 (or annexin V) is a cellular protein in the annexin group. In flow cytometry, annexin V is commonly used to detect apoptotic cells by its ability to bind to phosphatidylserine, a marker of apoptosis when it is on the outer leaflet of the plasma membrane.

Like other annexin types, annexin A-V can also be expressed on the cell surface and can function to form 2-dimensional crystals to protect the lipids of the cell membrane from involvement in coagulation mechanisms. Annexin V Blocking An additional control that may be performed includes preincubation of cell samples with recombinant unconjugated Annexin V, which is included as part of the Annexin V-FITC Apoptosis Detection Kit II (Cat. No 556570). Analyze annexin V-FITC binding by flow cytometry (Ex = 488 nm; Em = 350 nm) using FITC signal detector (usually FL1) and PI staining by the phycoerythrin emission signal detector (usually FL2).
