RUU-WAC2A reacts anti Human recombinant and enDogenous annexin A5. It shows no cross reactivity with Annexins I, II, III, IV, VI, VII and VIII in ELISA or in immunoprecipitation. It does not recognise Monkey and Rat Annexin V in ELISA.

Each vial contains 100 ul of 1 mg/ml purified antibody in PBS containing 0.09% sodium azide.

Store at 4 degree C, or in small aliquots at -20 degree C.

ELISA (EIA), Immunocytochemistry (IHC), Immunofluorescence (IF), Immunohistochemistry (IHC) (frozen), Immunohistochemistry (IHC) (paraffin)

The monoclonal antibody is suitable for ELISA in combination with a polyclonal antibody raised anti Annexin V in Rabbit. It can be applied in immunofluorescence to parafolmaldehyde fixed cell samples and in immunohistochemistry of frozen sections and formaldehyde fixed and paraffin embedded tissue specimens. For immunohistochemistry of paraffin sections a pretreatment step with 2% amino-propyl-triethoxysilan (in 100% ethanol) and 0,2 % BSA is recommended. The sections are heated for 15 minutes at 100 degree C in a citRate buffer (10 mM trisodium citRate, pH 6,0). The sections are then further processed by routine procedures (see below). RUU-WAC2a inhibits annexin A5 binding to anionic phospholipid-containing vesicles, activated platelets and apoptotic cells for more than 95%. Optimal antibody dilution should be determined by titRation; recommended range is 1:50 - 1:100 for immunohistochemistry with avidin-biotinylated Horseradish peroxidase complex (ABC) as detection reagent, and 1:100 - 1:500 for immunoblotting appliCations.

Source Note: RUU-WAC2a is a Mouse monoclonal IgG1 antibody obtained by fusion of P3-X63-Ag 8,653 Mouse myeloma cells with spleen cells from a BABL/c Mouse immunized with recombinant annexin A5.

Annexins, Apoptosis

Annexin A5 (or annexin V) is a cellular protein of the annexin family. Annexin A5 has been proposed to play a role in the inhibition of blood coagulation by competing for phosphatidylserine binding sites with prothrombin, and also to inhibit the activity of phospholipase A1. Annexin A5 forms a shield around negatively-charged phospholipid molecules, which blocks the entry of phospholipids into coagulation (clotting) reactions. Antibodies directed anti annexin A5 are the cause of the antiphospholipid syndrom in which the formation of the shield is disrupted by antibodies. Without the shield, there is an increased quantity of phospholipid molecules on cell membranes, speeding up coagulation reactions and causing the blood-clotting characteristic of the antiphospholipid antibody syndrome. Annexin A5 is used as a probe in the annexin A5 affinity assay to detect cells that have expressed phosphatidylserine on the cell surface, a feature found in apoptosis aswell as other forms of cell death (1,2). Platelets also expose phosphatidyl-serine on their surface when activated, which serves as binding site for various coagulation factors. Annexin A5 has been shown to interact with kinase insert domain receptor (3) and integrin beta 5 (4). RUU-WAC2a is a monoclonal that specifically reacts with annexin A5. This monoclonal antibody is directed to the phospholipid binding domain of annexin A5 and as such it inhibits annexin A5 binding to anionic phospholipid membranes for more than 95%. RUU-WAC 2A does not remove annexin A5 bound to phospholipid surfaces indiCating that the epitope is not accessible after interaction with annexin A5.

Prostaglandin Synthesis And Regulation Pathway (198912)

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]

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. Protein type: Apoptosis; Calcium-binding; Inhibitor; Lipid-binding. Chromosomal Location of Human Ortholog: 4q27. Cellular Component: focal adhesion; membrane; cytoplasm; intracellular; external side of plasma membrane. Molecular Function: phospholipase inhibitor activity; calcium-dependent phospholipid binding; phospholipid binding; calcium ion binding. Biological Process: response to organic substance; negative regulation of catalytic activity; blood coagulation; signal transduction; negative regulation of coagulation; negative regulation of apoptosis.
