  • 製品の概要

    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.

  • 研究分野

  • 機能

    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.
  • 組織特異性

    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.
  • 関連疾患

    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.
  • 配列類似性

    Belongs to the TGF-beta family.
  • 翻訳後修飾

    The precursor is cleaved into mature TGF-beta-1 and LAP, which remains non-covalently linked to mature TGF-beta-1 rendering it inactive.

  • 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.

  • Sandwich ELISA on rat blood serum using Abcam's TGF beta 1 Rat ELISA Kit (ab119558).

  • Representative Standard Curve using ab119558.

Thank you for contacting us.

Here is the correct protocol section:

Prepare your serum and plasma samples before starting the test
procedure. Dilute serum and plasma samples with Assay Buffer (1x)
according to the following scheme:
- 20 μl sample + 920 μl Assay Buffer (1x)
- Add 30 μl 1N HCl to 940 μl prediluted sample, mix and incubate for
1 hour at room temperature.
- Neutralize by addition of 30 μl 1N NaOH.
Prepare your cell culture supernatant samples before starting the test
procedure. Dilute cell culture supernatant samples with Assay Buffer
(1x) according to the following scheme:
- 20 μl sample + 180 μl Assay Buffer (1x)
- Add 20 μl 1N HCl to 200 μl prediluted sample, mix and incubate for
1 hour at room temperature.
- Neutralize by addition of 20 μl 1N NaOH.

The table is correct.

I am very sorry for this mistake and the confusion caused.
Please let me know how the results turned out.

If the data are incorrect or do not make any sense, please let me know your order or PO number as we made a mistake on our end and would like to remedy that by replacing the kit free of charge.
I look forward to hear back from you.

We have not tested bronchoalveolar lavage fluid with ab119558, so we do not have a recommended dilution for this sample type. If you perform a literatire search to determine the expected levels of TGF beta 1 in this fluid compared to serum, plasma, or cell culture supernatant, then you can use the expected level as a guide to what dilution to use.

We always recommend testing multiple different dilutions of your sample to ensure that the readings fall within the range of the standard curve.

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.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

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 out to us.

Thank you again for your patience.

I've just heard back from the lab, andstandard should be reconstituted in 400 ulto a concentration of400 pg/ml.

Please let me know if you have further questions or if there is anything else we can do. Have a great day.
