• Product name
    Anti-SOX9 antibody - ChIP Grade
    See all SOX9 primary antibodies
  • Description
    Rabbit polyclonal to SOX9 - ChIP Grade
  • Specificity
    The antibodies were evaluated for specificity with a dot blot assay using synthetically prepared SOX9 peptides. By immunoblot analysis, a ~65 kDa immunoreactive protein from mouse embryo cell lysate was detected (sample were boiled prior to subject 10% SDS-polyacrylamide gel electrophoresis). This band is abolished by the depletion of the synthetic peptide.

  • Function
    Plays an important role in the normal skeletal development. May regulate the expression of other genes involved in chondrogenesis by acting as a transcription factor for these genes.
  • Involvement in disease
    Defects in SOX9 are the cause of campomelic dysplasia (CMD1) [MIM:114290]. CMD1 is a rare, often lethal, dominantly inherited, congenital osteochondrodysplasia, associated with male-to-female autosomal sex reversal in two-thirds of the affected karyotypic males. A disease of the newborn characterized by congenital bowing and angulation of long bones, unusually small scapulae, deformed pelvis and spine and a missing pair of ribs. Craniofacial defects such as cleft palate, micrognatia, flat face and hypertelorism are common. Various defects of the ear are often evident, affecting the cochlea, malleus incus, stapes and tympanum. Most patients die soon after birth due to respiratory distress which has been attributed to hypoplasia of the tracheobronchial cartilage and small thoracic cage.

Anti-SOX9 antibody - ChIP Grade images

  • ChIP analysis of 15P-1 cells using no antibody (lane 1), a control rabbit IgG (lane 2) or ab3697 (lane 3). DNA from the Er71 promoter (-334 to +28), an Er71 region ranging from exon 6 to exon 7, or the 3'-UTR of Sox9 (2664–3023) was PCR amplified.
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human skin hair follicles labling SOX9 with ab3697. Hematoxylin purple nuclear conterstain.

  • IHC-P image of SOX9 (ab3697) on E11.5 mouse embryo sections. The sections were fixed in paraformaldehyde and underwent heat mediated antigen retrieval using Tris/EGTA (pH9). The sections were then blocked in 1% BSA solution for 30 mins at 20°C. In these images, ab3697 can be seen staining nuclei on the lumen surface of the brain (green).

  • IHC image of SOX9 staining in mouse e14 whole foetus formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol B. 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 ab3697, 1µg/ml, for 15 mins at room temperature. A goat anti-rabbit biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC 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.

I do think IP is a good idea, though you will see some strong signal at 50 and 25 kDa, if your secondary anti-rabbit secondary IgG detects denatured rabbit IgG, which will be in the IP product. It may not be a problem if the band of interest is near 56...
