Target

  • Function

    Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation.
  • Involvement in disease

    Genetic variations in TNF are a cause of susceptibility psoriatic arthritis (PSORAS) [MIM:607507]. PSORAS is an inflammatory, seronegative arthritis associated with psoriasis. It is a heterogeneous disorder ranging from a mild, non-destructive disease to a severe, progressive, erosive arthropathy. Five types of psoriatic arthritis have been defined: asymmetrical oligoarthritis characterized by primary involvement of the small joints of the fingers or toes; asymmetrical arthritis which involves the joints of the extremities; symmetrical polyarthritis characterized by a rheumatoidlike pattern that can involve hands, wrists, ankles, and feet; arthritis mutilans, which is a rare but deforming and destructive condition; arthritis of the sacroiliac joints and spine (psoriatic spondylitis).
  • Sequence similarities

    Belongs to the tumor necrosis factor family.
  • Post-translational
    modifications

    The soluble form derives from the membrane form by proteolytic processing.
    The membrane form, but not the soluble form, is phosphorylated on serine residues. Dephosphorylation of the membrane form occurs by binding to soluble TNFRSF1A/TNFR1.
    O-glycosylated; glycans contain galactose, N-acetylgalactosamine and N-acetylneuraminic acid.
  • Cellular localization

    Secreted and Cell membrane.
  • Target information above from: UniProt accession P01375 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010

The cells were fixed with methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab1793, 1/10 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a decreased signal in RAW 264.7 cells fixed with 4% paraformaldehyde (10 min) used under the same conditions.

    Please note that Abcam do not have data for use of this antibody on non-fixed cells. We welcome any customer feedback.

Thank you for your reply. Are you working in any species or applications other than WB on human samples? We have a large number of antibodies to TNF alpha that are guaranteed for that purpose. For example, our rabbit polyclonal antibodies ab6671 and ab9739 have good customer feedback and have been used in a number of publications. Please let me know which antibody you would like to receive and I will be happy to process your replacement.

Question

May I ask you a help,

Actually I have received the Anti-TNF alpha antibody [52B83] (ab1793) from you this week and I am trying to detect the TNF-alpha that is supposed to be overexpressed in some transfected cells, but after the W.B. I got strange bands around 40 KD and no bands at the position of 17 KD. I attched the fim after 5 min exposure.

Please, would you explain this to me.

Asked on Aug 13 2012

Answer

Thank you for contacting us. While TNF-alpha is known to form a homotrimer, the expected molecular weight for that band would be around 58 kDa. In order to help determine the nature of the bands you are observing, it would be helpful if you could please provide some additional details about your protocol.

1.) What type of cells were you staining, and what species was the transfected TNF alpha? Was the transfected protein tagged? What is the difference between the samples in lanes 1 / 2 and lanes 3 / 4?

2.) How were the cells lysed, how much protein was loaded per lane, and were the samples reduced and denatured?

3) What blocking agent was used?

4) What was the primary antibody dilution and incubation time?

5) What secondary antibody was used, what was the dilution and incubation time, and has this secondary antibody been working well with other primary antibodies?

6) What was your original order or PO number?

I will be happy to help you further once I have this additional information.

Asked on Jul 05 2012

Answer

Thats no problem at all. I'm glad you have found the information of help.

I am sorry that using the discount code online has not proved very straight forward. What you need to do is simply put in a normal order and add the discount code in the "Notes" section. Once the order has been received by us the price of the antibody will then be removed after we have checked that the code is valid. The code is active as soon as the Abreview has been submitted.

If you would like, I could set up the order for you? All I need is the delivery address and if you have a particular account with us you would like it set up on as well as the antibody you wish to purchase.

I look forward to receiving your reply.

Asked on Jul 04 2012

Answer

Thank you for your patience. I can now share some further information with you relating to the anti-TNF alpha antibodies ab1793 and ab9739.

In short, I think either antibody should detect the soluble form of the TNF alpha in your samples. I have the following specific information in regards to each antibody:

Mouse monoclonal ab1793

This antibody has been produced from the hybridoma clone 52B83 and its properties have been characterised and published in the following article:

Gerspach, J et al; Detection of membrane-bound Tumor Necrosis Factor (TNF): an analysis of TNF-specific reagents. Microsc Res Tech 2000, 50: 243

It has been found that this antibody is able to detect both the free soluble form (˜17 kDa) of TNF alpha as well as the membrane bound form (˜26 kDa). However, it does not detect the TNR-R1 or TNF-R2 receptor boundTNF.

In both of the customer reviews that we have for this antibody where human samples were used, only the full length, membrane bound form was observed by Western blotting:

https://www.abcam.com/TNF-alpha-antibody-52B83-ab1793.html&tab=abreviews&intabreviewid=19555

Rabbit polyclonal ab9739

This antibody has been raised against the C-terminal extracellular domain of TNF alpha. The sequence is as follows:

MLRSSSQNSS DKPVAHVVAN HQVEEQLEWL SQRANALLAN GMDLKDNQLV VPADGLYLVY SQVLFKGQGC PDYVLLTHTV SRFAISYQEK VNLLSAVKSP CPKDTPEGAE LKPWYEPIYL GGVFQLEKGD QLSAEVNLPK YLDFAESGQV YFGVIAL

This antibody should therefore detect both the soluble form (˜17 kDa)and membrane bound form (˜26 kDa).

In thecustomer reviews that we have for this antibody it seems the soluble form of the protein is detected with a band of ˜17 kDa:

I think I would suggest trying ab9739 over ab1793 as this has consistently showndetection of the 17 kDa product in many different samples.

I hope this information has been of help. If you have any further questions please do not hesitate to ask.

Question

Dear Sir or Madam, We ordered a tnf-alpha antibody from your company which cat:ab1793 and lot: GR1835. We use this antibody detected the protein coms from the cortex of C57BL/6 mouse. We only find a band near 37 kDa, otherwise your Date sheet shows "It reacts with free soluble (17 kDa) and membrane (26 kDa) human TNF-alpha". Would you like tell us the difference between our results and yours? Attached is our results

Answer

Thank you for contacting us.

This particular antibody reacts with free soluble (17 kDa) and membrane (26 kDa) human TNF-alpha but not with receptor-bound TNF-alpha. These values are the predicted molecular weights of the free soluble and membrane bound proteins. Real would sizes can and often are much different then these predicted sizes as post translational modifications of the protein will occur. A difference of 5-10kDA from predicted size can be common with many proteins.

While we do guarantee this product to recognize TNF-alpha in western blot, this application is not directly tested by us but is based from numerous publications and Abreviews in which this product was used in WB.
A list of publications may be found here:https://www.abcam.com/TNF-alpha-antibody-52B83-ab1793-references.html

Our Abreviews may be found here: https://www.abcam.com/TNF-alpha-antibody-52B83-ab1793-reviews.html

I have noted that in some of the Abreviews which have been submitted by our customers using this product in WB, the size of the band is similar to what you have been seeing. In particular this Abreview on human MCF-7 cells shows a similar response:

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