General description
Annexin A2 (UniProt: P07355; also known as Annexin II;Annexin-2;Calpactin I heavy chain;Calpactin-1 heavy chain;Chromobindin-8;Lipocortin II;Placental anticoagulant protein IV (PAP-IV);Protein I;p36) is encoded by the ANXA2 (also known as ANX2, ANX2L4, CAL1H, LPC2D) gene (Gene ID: 302) in human. Annexin A2 belongs to the annexin family of calcium-dependent phospholipid-binding proteins, and is a multifunctional protein involved in a wide range of biological processes. It is characterized by a conserved core domain that mediates membrane binding and a unique N-terminal tail that confers specific protein-protein interactions. The core domain contains four annexin repeats, each forming a five alpha-helix bundle, while the N-terminal tail varies among the annexins and is responsible for the diverse functions of Annexin A2. Annexin A2 functions both intracellularly and extracellularly. Intracellularly, it plays a role in various cellular processes including membrane trafficking, endocytosis, exocytosis, and the organization of the actin cytoskeleton. It acts as an anticoagulant by inhibiting prothrombin activation. Extracellularly, Annexin A2 can act as a receptor for plasminogen and tissue plasminogen activator on the cell surface, facilitating the conversion of plasminogen to plasmin, a key enzyme in fibrinolysis and wound healing. Annexin A2 has been implicated in a variety of diseases. Its role in promoting angiogenesis and stabilizing blood vessels links it to cancer, where it can influence tumor growth, metastasis, and angiogenesis. In cardiovascular disease, its anticoagulant properties are significant, and alterations in its function or expression levels can lead to thrombotic events. Additionally, its involvement in fibrinolysis and inflammation connects it to autoimmune diseases and conditions such as rheumatoid arthritis. Annexin A2 has also been studied in neurodegenerative diseases, where its interaction with cytoskeletal elements suggests a potential role in neuroinflammation and cell death. This ZooMAb® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected Annexin A2 in L6 cells.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.
Biochem/physiol Actions
Clone 1C4 is a ZooMAb® recombinant rabbit monoclonal antibody that detects Annexin A2. It targets an epitope within 24 amino acids from the internal region.
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
