• Product name
  • Description
    Rabbit polyclonal to TGF beta 1
  • Host species
  • Specificity
    Full length, inactive 44 kD TGFB1 is cleaved into mature TGFB1 (13 kD). TGFB1 also homodimerizes and heterodimerizes with TGFB2, so there is potential for multiple different band sizes in WB.
  • Tested applications
    Suitable for: Flow Cyt, IHC-P, WBmore details
  • Species reactivity
    Reacts with: Mouse, Human
    Predicted to work with: Sheep, Rabbit, Horse, Guinea pig, Hamster, Cow, PigDoes not react with: Dog
  • Immunogen

    Synthetic peptide corresponding to Human TGF beta 1.


  • Positive control
    • WB: Recombinant human TGF beta 1.



Our Abpromise guarantee covers the use of ab9758 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. PubMed: 25421510
IHC-P Use at an assay dependent concentration. PubMed: 25207642
WB 1/100 - 1/500.

In reduced samples, the expected bands are 12 kDa (mature protein) and 44 kDa (unprocessed protein). Expected band at 25 kDa in non-reduced samples (homodimer of mature protein). Glycosylations may also cause unprocessed protein to run a few kDa higher (around 50 kDa). TGFB1 also heterodimerizes with TGFB2, so there is potential for multiple different band sizes in WB.


  • Function
    Multifunctional protein that controls proliferation, differentiation and other functions in many cell types. Many cells synthesize TGFB1 and have specific receptors for it. It positively and negatively regulates many other growth factors. It plays an important role in bone remodeling as it is a potent stimulator of osteoblastic bone formation, causing chemotaxis, proliferation and differentiation in committed osteoblasts.
  • Tissue specificity
    Highly expressed in bone. Abundantly expressed in articular cartilage and chondrocytes and is increased in osteoarthritis (OA). Co-localizes with ASPN in chondrocytes within OA lesions of articular cartilage.
  • Involvement in disease
    Defects in TGFB1 are the cause of Camurati-Engelmann disease (CE) [MIM:131300]; also known as progressive diaphyseal dysplasia 1 (DPD1). CE is an autosomal dominant disorder characterized by hyperostosis and sclerosis of the diaphyses of long bones. The disease typically presents in early childhood with pain, muscular weakness and waddling gait, and in some cases other features such as exophthalmos, facial paralysis, hearing difficulties and loss of vision.
  • Sequence similarities
    Belongs to the TGF-beta family.
  • Post-translational
    The precursor is cleaved into mature TGF-beta-1 and LAP, which remains non-covalently linked to mature TGF-beta-1 rendering it inactive.
  • Cellular localization
    Secreted > extracellular space > extracellular matrix.

    Lysates/proteins at 0.25 µg per lane.

    All lanes : Peroxidase-conjugated anti-rabbit IgG at 1/40000 dilution

    Observed band size: 12,25 kDa (why is the actual band size different from the predicted?)

    Incubated with the primary antibody overnight at 4°C.

    Incubated with the secondary antibody for 30 min at room temperature.

  • Five micron sections of paraffin embedded peritoneum tissue were mounted onto electrostatically charged microscope slides and dewaxed in xylene (2×5min) and rehydrated. Antigens were retrieval by pressure-cooking slides in 10 mM Tris 1 mM EDTA pH 9, for 5 mins. Slides were washed in H2O before incubation with 3% hydrogen peroxide for 30 min. Slides were blocked then incubated with ab9758 diluted 1/1000 or rabbit IgG in blocking buffer overnight at 4°C. Slides were washed in TBST20 and incubated for 30 min with secondary antibody and washed again before incubation with 3, 3′-diaminobenzidine for 5 min. Slides were then counterstained with hematoxylin, dehydrated and visualized by light microscopy, using an Olympus Provis microscope equipped with a Kodak DCS330 camera.
