  • Product name
  • Description
    Rabbit polyclonal to Galectin 7
  • Tested applications
    Suitable for: WB, IP, ICC/IF, IHC-Pmore details
  • Species reactivity
    Reacts with: Mouse, Human
    Predicted to work with: Chimpanzee, Gorilla, Orangutan
  • Immunogen

    Immunogen was a synthetic peptide, which represented a portion of human Lectin, Galactoside-binding 7 encoded within exon 4 (LocusLink ID 3963).

  • Positive control
    • Modified RIPA extract from the epidermis of FVB wild-type or galectin 7 transgenic mice.
  • General notes


    The galectins are a family of beta-galactoside-binding proteins implicated in modulating cell-cell and cell-matrix interactions. Differential and in situ hybridizations indicate that this lectin is specifically expressed in keratinocytes. It is expressed at all stages of epidermal differentiation (i.e., in basal and suprabasal layers). The protein was found mainly in stratified squamous epithelium. It is moderately repressed by retinoic acid. The antigen localized to basal keratinocytes, although it was also found at lower levels in the suprabasal layers, where it concentrated to areas of cell-to-cell contact. The cellular localization and its striking down-regulation in cultured keratinocytes imply a role in cell-cell and/or cell-matrix interactions necessary for normal growth control.

    ab10481 detection of mouse galectin 7 by Western blot and immunoprecipitation. Samples: A. Modified RIPA extract (10 µg) from the epidermis of FVB wild-type (wt) or galectin 7 transgenic (TG) mice. B. Modified RIPA extract (20 µg) from the epidermis of FVB wild-type mice. Antibody: ab10482 used at 0.005 (A) or 0.0025 (B) µg/ml for WB and as indicated for IP. Detection: Chemiluminescence with 1 second exposure time.
  • ab10482 staining Galectin7 in Human cervical tumor and immortalized keratinocytes by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with 0.25% Triton X-100/PBS and blocked with 1% BSA for 1 hourat 25°C. Samples were incubated with primary antibody (1/1000 in 1% BSA/PBS) for 24 hours at 4°C. An Alexa Fluor®594-conjugated Goat anti-rabbit IgG polyclonal (1/2000) was used as the secondary antibody.
    SiHa cells (negative control - very low Gal-7 mRNA)
    Immortilized keratinocytes (positive control - high Gal-7 mRNA)
  • IHC image of ab10482 staining in human Hodgkin's lymphoma formalin fixed paraffin embedded tissue section, performed on a Leica 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 ab10482, 5µg/ml, for 15 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.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
