Properties

Applications

Our Abpromise guarantee covers the use of ab227486 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Flow Cyt Use at an assay dependent concentration.
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.

IHC is not recommended in human or rat due to nonspecific or negative staining.

WB Use at an assay dependent concentration. Detects a band of approximately 36, 34 kDa (predicted molecular weight: 38 kDa).
IP Use at an assay dependent concentration.

Target

  • Function

    Calcium-regulated membrane-binding protein whose affinity for calcium is greatly enhanced by anionic phospholipids. It binds two calcium ions with high affinity. May be involved in heat-stress response.
  • Sequence similarities

    Belongs to the annexin family.
    Contains 4 annexin repeats.
  • Domain

    A pair of annexin repeats may form one binding site for calcium and phospholipid.
  • Post-translational
    modifications

    Phosphorylation of Tyr-24 enhances heat stress-induced translocation to the cell surface.
    ISGylated.
  • Cellular localization

    Secreted > extracellular space > extracellular matrix > basement membrane. Melanosome. In the lamina beneath the plasma membrane. Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Translocated from the cytoplasm to the cell surface through a Golgi-independent mechanism.

  • Flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol-permeabilized HeLa (human epithelial cell line from cervix adenocarcinoma) cell line labeling Annexin-2/ANXA2 with ab189473 at 1/500 dilution (red) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) at 1/2000 dilution was used as the secondary antibody.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab189473).

  • Annexin-2/ANXA2 was immunoprecipitated from 0.35 mg of NIH/3T3 (mouse embryo fibroblast cell line) whole cell lysate with ab189473 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab189473 at 1/2000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

    Lane 1: NIH/3T3 whole cell lysate 10 µg (Input). 

    Lane 2: ab189473 IP in NIH/3T3 whole cell lysate. 

    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab189473 in NIH/3T3 whole cell lysate.

    Exposure time: 1 second.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab189473).

  • Immunohistochemical analysis of paraffin-embedded mouse liver tissue labeling Annexin-2/ANXA2 with ab189473 at 1/5000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) Ready to use. Positive staining on the sinusoid of mouse liver (PMID: 23188673). Counter stained with hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) Ready to use.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab189473).

    Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
