Annexin V apoptosis assay. 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.
The Annexin V conjugate may be used in Flow Cytometry or in other in situ detection methods to facilitate the rapid and early detection of cell surface changes associated with apoptosis. Annexin V binding to PS occurs only in dying cells, is calcium dependent, and reversible. Each Annexin V molecule binds approximately 50 exposed PS monomers.
88-8103, 88-8007, 88 Annexin V specifically binds to phosphatidylserine in the presence of protein-dependent Ca ion. By using fluorescent-labeled Annexin V, the apoptotic cells can be identified by flow cytometry or fluorescence microscopy. Experimental Data: Fig. 1 Fluorescent imaging of apoptosis induced cells Annexin V fluorescent conjugates can be used to detect apoptotic cells. The human anticoagulant Annexin V is a 35-36 kDa calcium-dependent phospholipid-binding protein with high affinity for phosphatidylserine (PS). In normal viable cells, PS is located on the inner leaflet of the cytoplasmic membrane.
Förordning (EG) nr The aim of this trial will be to test and validate the value of scintigraphy with injection of 99mTc-Annexin-V-128 for the detection of complicated carotid plaques. Monitoring of membrane phospholipid scrambling in human erythrocytes and K562 cells with FM1-43 – a comparison with annexin V-FITC. A Wróbel, Margo av E Hagforsen · 2017 · Citerat av 6 — For the evaluation of apoptosis/necrosis, the cells were stained with Annexin V Alexa Fluor 594 and Draq7 for 10 min, and then immediately Annexin V-FITC Early Apoptosis Detection Kit. Kit Komponent. Annexin V-FITC Conjugate. 10X Annexin V Binding Buffer. Propidium Iodide (PI) Solution. Apoptosis was assessed by the terminal deoxynucleotidyl dUTP nick end labeling (TUNEL) assay and Annexin V flow cytometry, and caspase-3 and poly Factors such as low serum adiponectin (Shojaie et al., 2009) and annexin V levels (Shojaie et al., 2009), infectious diseases such as Mycoplasma pneumonia Kan Annexin V vara inblandad i Ledgångsreumatikers högre risk för att drabbas av hjärt- och kärl sjukdomar?
The Annexin V-FITC Kit contains reagents for the simultaneous fluorescent detection of apoptotic, necrotic, and dead cells through the specific binding of FITC-labeled Annexin V to phosphotidylserine (PS). The kit consists of Annexin V-FITC, Annexin V Binding Buffer, and Propidium Iodide Solution.
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.
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).

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).
> Annexin V negative - PI negative populations are healthy cells. > Annexin V positive - PI negative populations represent cells in early apoptosis. > Annexin V positive - PI positive staining indicate cells are in necrosis (post-apoptotic necrosis or late apoptosis).

Annexin V is one of few proteins that bind heparin in a calcium-dependent manner (78) as verified by X-ray crystallography (79).
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.
This apoptosis lecture explains about the structure and function of annexin v in apoptosis or cell death. For more information, log on to-http://www.shomusbi 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 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.
