Our Abpromise guarantee covers the use of ab226091 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
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.

Heat up to 98°C, below boiling, and then let cool for 10-20 min.

WB Use at an assay dependent concentration. Detects a band of approximately 78-100 kDa (predicted molecular weight: 90 kDa).
  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      Component of SUN-protein-containing multivariate complexes also called LINC complexes which link the nucleoskeleton and cytoskeleton by providing versatile outer nuclear membrane attachment sites for cytoskeletal filaments. Required for interkinetic nuclear migration (INM) and essential for nucleokinesis and centrosome-nucleus coupling during radial neuronal migration in the cerebral cortex and during glial migration. Anchors chromosome movement in the prophase of meiosis and is involved in selective gene expression of coding and non-coding RNAs needed for gametogenesis. Required for telomere attachment to nuclear envelope and gametogenesis. Helps to define the distribution of nuclear pore complexes (NPCs).
    • Sequence similarities

      Contains 1 SUN domain.
    • Domain

      The SUN domain may play a role in the nuclear anchoring and/or migration.
    • Cellular localization

      Nucleus inner membrane.

    • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast tissue sections labeling SUN1 with purified ab124770 at 1/200 dilution (0.698 µg/ml). Perform heat mediated antigen retrieval using Citrate buffer, pH 6.0. ImmunoHistoProbe one step HRP Polymer (ready to use) was used as the secondary antibody. Negative control: PBS instead of the primary antibody. Hematoxylin was used as a counterstain.
      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab124770)
    • ab124770, at 1/100 dilution, staining SUN1 in paraffin-embedded Human ovary carcinoma tissue by Immunohistochemistry.

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab124770).

      Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
