ターゲット情報

  • 機能
    Controls reversibly actin polymerization and depolymerization in a pH-sensitive manner. It has the ability to bind G- and F-actin in a 1:1 ratio of cofilin to actin. It is the major component of intranuclear and cytoplasmic actin rods.
  • 組織特異性
    Widely distributed in various tissues.
  • 配列類似性
    Belongs to the actin-binding proteins ADF family.
    Contains 1 ADF-H domain.
  • 翻訳後修飾
    Phosphorylated on Ser-3 in resting cells.
  • 細胞内局在
    Nucleus matrix. Cytoplasm > cytoskeleton. Almost completely in nucleus in cells exposed to heat shock or 10% dimethyl sulfoxide.

    Predicted band size : 19 kDa
    Observed band size : 20 kDa (why is the actual band size different from the predicted?)
  • ICC/IF image of ab42824 stained human HeLa cells. The cells were PFA fixed (10 min), permabilised in TBS-T (20 min) and incubated with the antibody (ab42824, 1µg/ml) for 1h at room temperature. 1% BSA / 10% normal serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).

  • IHC image of Cofilin staining in human breast carcinoma FFPE section, performed on a BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab42824, 1µg/ml, for 8 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    Exposure time : 30 seconds

    This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab42824 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.

Thank you for your reply.

Neither ab42824 or ab12866 show any cross reactivity with either Destrin (ADF) or phosphor Destrin. As neither of these antibodies has been shown to work on monkey tissue then they are both eligible for our testing d...
