  • Product overview

    Abcam’s TGF beta 1 Rat in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for accurate quantitative measurement of Rat TGF beta 1 concentrations in Cell culture supernatant, serum and plasma (EDTA and heparin).

    Rat TGF beta 1 specific antibodies have been precoated onto 96-well plates. Standards and test samples are added to the wells and then incubated at room temperature. After washing, a Biotin-conjugated anti-Rat TGF beta 1 detection antibody is added then incubated at room temperature. Following washing Streptavidin-HRP conjugate is added to each well, incubated at room temperature then again washed. TMB is added and then catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of Rat TGF beta 1 captured on the plate.

  • FunctionMultifunctional 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 specificityHighly 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 diseaseDefects 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 similaritiesBelongs 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 localizationSecreted > extracellular space > extracellular matrix.

  • Activated TGF-beta 1 measured in tissue lysates, homogenised in RIPA buffer, activated (20 uL of HCl  per 20 uL of samples with 180 uL of buffer) and tested between 25-250 ug protein per mL. Data expressed as TGF beta per mg of extracted protein (duplicates +/- SD).

  • Activated TGF-beta 1 measured in rat biological fluids (dilution range 1/50-1/200; duplicates +/- SD). Human and mouse samples, diluted 1:12, gave results below the level of detection.

TGF-beta ELISA assay kit in rat blood serum is very very excellent and easy step.
But, color development is very quickley disappears after stop solution.

Thank you for contacting us.

Our TGF beta 1 Rat ELISA Kit will detect the inactive ( which get activated during the sample preparation (HCL and NaOH)) and active form.

It will not detect the LAP complex.

Thank you for contacting us.
I can confirm that the volume to be added is 400 ul.
The "2 x" is an oversight on our end due to the fact that 2 vials are being sent.
I will look into having this corrected.
Thank you for pointing this ...
