Fast and convenient
EGFP is a bright and photo-stable green fluorescent protein and the kit can differentiate apoptosis vs necrosis when performing both annexin V-EGFP and PI staining
Shelf Life: 12 months
Background: The Annexin V-EGFP Apoptosis Detection Kit is based on the observation that soon after initiating apoptosis, most cell types translocate the membrane phospholipid phosphatidylserine (PS) from the inner face of the plasma membrane to the cell surface. Once on the cell surface, PS can be easily detected by staining with an enhanced green fluorescent protein (EGFP) fusion of annexin V, a protein that has a strong natural affinity for PS. The one-step staining procedure takes only 10 minutes. In addition, the assay can be directly performed on live cells. Detection can be analyzed by flow cytometry or by fluorescence microscopy with a FITC filter. EGFP is brighter and more photo-stable than other fluorescent reagents. The kit can differentiate apoptosis vs necrosis when performing both annexin V-EGFP and PI staining.
Summary: Detection method- Flow cytometry (Ex = 488 nm; Em = 530 nm) and fluorescence microscopy
Species reactivity- Mammalian
Kit size- 25, 100, 400
Applications-Detect early/middle stages of apoptosis; differentiate apoptosis from necrosis.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene belongs to the annexin family of calcium-dependent phospholipid binding proteins some of which have been implicated in membrane-related events along exocytotic and endocytotic pathways. Annexin 5 is a phospholipase A2 and protein kinase C inhibitory protein with calcium channel activity and a potential role in cellular signal transduction, inflammation, growth and differentiation. 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 and a protein product with a molecular weight of about 35 kDa. [provided by RefSeq, Jul 2008]
Uniprot Description
ANXA5: a calcium/phospholipid-binding protein and an anticoagulant protein that acts as an indirect inhibitor of the thromboplastin-specific complex, which is involved in the blood coagulation cascade. The binding of labeled ANXA5 to phosphatidylserine is used as a marker of apoptosis. Annexins are a family of structurally related proteins whose common property is calcium-dependent binding to phospholipids. There are at least ten different annexins in mammalian species. Annexins do not contain signal peptides, yet some annexins (A1, A2 and A5) appear to be secreted in a physiologically regulated fashion.

Product Notes
The ANXA5 anxa5 (Catalog #AAA841775) is an Assay Kit and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "Annexin V, Assay Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
