Our Abpromise guarantee covers the use of ab64715 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-FoFr 1/250.
WB Use a concentration of 1 - 2 µg/ml. Use under non reducing condition. Detects a band of approximately 45 kDa (predicted molecular weight: 45 kDa).

The detection limit for hTGF beta 1 is ~5ng/lane under non-reducing conditions. 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.

ELISA Use a concentration of 2 - 8 µg/ml. Using 100µl/well will detect ~30-2000pg/ml
IHC-Fr Use a concentration of 8 - 25 µg/ml.
Neutralising Use a concentration of 0.3 - 1 µg/ml. This dilution will neutralize 50% of the bioactivity due to 0.25ng/ml of rhTGF beta 1, using the HT2 cell line.
Flow Cyt Use a concentration of 25 µg/ml.

ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.

  • Application notes
    Is unsuitable for IHC-P.
  • Target

    • 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.

      Tissue lysates were denatured for 10-15 minutes at 90ºC. Blot was performed under non-reducing conditions. ab64715 was incubated overnight at 4ºC and the secondary antibody for 1 hour at RT.

    • IHC-FoFr image of TGF beta 1 staining on sections from rat brain using ab64715 (1:250). The rat was treated with LPS and focal brain injury. 72 hours after injury, the rat was perfused with 4%PFA in 0.1M PBS. Antibody staining was performed on sections using free floating technique.

    • Human PC-3 cells were stained with ab64715 (filled histogram) or isotype control antibody (open histogram) followed by IgG (APC) anti-mouse antibody.
    • Approximately 0.3-1ug/ml of ab64715 will neutralize 50% of the bioactivity due to 0.25ng/ml of rhTGF-b1.
    • ab64715 inhibits the mIL-4-dependent 3H-thymidine incorporation by HT-2 cells in a dose-dependent manner. The ED50 for this effect is typically 0.02-0.06ng/ml.
