Anti-IL-1 alpha 抗体 (ab7632)

Thank you for contacting us. We are happy to help customers find the most positive control for their research purposes; however we are not specialized in this particular field and do not want to recommend a control that may be unsuitable. I believe that THP-1 cells can be used as positive control since they produce IL1. But I think that they also have to be stimulated in the right way to achieve proper IL1 production. This has not been tested experimentally by us. Maybe this publication will provide more information about this: http://onlinelibrary.wiley.com/doi/10.1002/ddr.1171/abstract We encourage customers to consult the latest literature available through PubMed and other resources in order to find the most up-to-date information about their specific research interests. I am sorry that I could not be more helpful, but I hope that the available literature in this area can provide some clarification. Please do not hesitate to contact us again with other needs or with any questions about our products.

Thank you for your message.

I am sorry to confirm that this antibody has not been specifically tested on human oral cancer tissue as far as I am aware.

I have done a search and I am sorry I cannot find information to confirm the expression of IL-1 alpha from oral cancer tissue. I would also expect this may depend on the specific type of oral cancer, and I can suggest the customer could consider a further literature search to confirm more details before they start their project.

I can also recommend that if they are not sure of the expression level of IL-1 alpha in their samples, then it would be important to include a positive control tissue sample such as human lymph node or thymus. We have slides available:

ab30146 Thymus (Human) Tissue Lysate - adult normal tissue

I hope this will be helpful to you. If you have any further questions, please do not hesitate to contact me. I look forward to receiving the completed questionnaire.

I am not aware that the positive control directions of this antibody have been updated, we currently recommend: Supernatants or lysates of 2 x 106 endotoxin-stimulated human peripheral blood mononuclear cells (PBMC)(PBMC stimulated for 24 hours with 1% (v/v) human serum plus 10 ng/mL E.coli LPS). For use as a positive control. As I mentioned in my previous email the following study used pancreatic tissue from cancerous tissue. IL1-alpha was not present in non-cancerous tissue. As IL-1 alpha is involved in the inflammatory response it may be that it is not abundantly present in normal tissue but I have found reference to both spleen tissue and human fetal skin being used as positive controls. Tjomsland V et al. Interleukin 1a sustains the expression of inflammatory factors in human pancreatic cancer microenvironment by targeting cancer-associated fibroblasts. Neoplasia 13:664-75 (2011).. PubMed: 21847358 The following products may therefore be of use as positive controls: https://www.abcam.com/Pancreas-tumor-human-adenocarcinoma-tissue-slides-ab5036.html https://www.abcam.com/Skin-human-fetal-normal-tissue-slides-ab4417.html and https://www.abcam.com/Spleen-human-normal-tissue-slides-ab4372.html I hope this information has been of help. If you have any further questions please do not hesitate to contact us again.     I hope this information has been of help. If you have any further questions please do not hesitate to ask.

This antibody has been used for staining of paraffin embedded human pancreas tissue: Tjomsland V et al. Interleukin 1a sustains the expression of inflammatory factors in human pancreatic cancer microenvironment by targeting cancer-associated fibroblasts. Neoplasia 13:664-75 (2011).  PubMed: 21847358 This study used tissue sections from pancreatic ductal adenocarcinoma patients. I am sorry that this has not been reflected on the datasheet. I am in the process of amending this. I am therefore not able to provide a conventional testing discount, however as the datasheet does not currently have any images presented for this application I can offer a testing discount if the customer agrees to provide an image through the Abreview system. If your customer would be interested in this please let me know and I will issue the testing discount.

Thank you for your call today and for your interest in these antibodies. Since we don't have any TNF alpha, IL1 alpha, or IL10 antibodies tested in squirrel samples, I can offer discounts off a future purchase if you buy these antibodies now, test squirrel, and submit feedback to us in the form of an Abreview. Each discount would be worth 1 free primary antibody. If you are interested in this offer, please follow these steps: 1. Reply to this e-mail to let me know that you would like to proceed and test these antibodies in squirrel. I will then send a discount code for each antibody. These codes must be issued before purchasing the antibodies so please wait for my reply before ordering. 2. Purchase the antibodies either by phone, fax, or online (www.abcam.com). 3. Test in squirrel. 4. Let us know the results, positive or negative, using our Abreview system (this will take about 10 minutes and images are great if you have them!).
