Application Abreviews Notes
ICC/IF Use at an assay dependent concentration. PubMed: 24950657
WB 1/500 - 1/1000. Detects a band of approximately 75 kDa (predicted molecular weight: 65 kDa).
IHC-P 1/100 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • Function

    Receptor for interleukin-1 alpha (IL-1A), beta (IL-1B), and interleukin-1 receptor antagonist protein (IL-1RA). Binding to the agonist leads to the activation of NF-kappa-B. Signaling involves formation of a ternary complex containing IL1RAP, TOLLIP, MYD88, and IRAK1 or IRAK2.
  • Sequence similarities

    Belongs to the interleukin-1 receptor family.
    Contains 3 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 TIR domain.

Thank you for contacting us and your interest in our products. xxxx passed on your query to the Scientific Support team and I will endeavour to answer yourquestion as bestI can.

We have a couple of antibodies which may be suitable for the experiments you are hoping to perform. https://www.abcam.com/IL1-beta-antibody-Biotin-ab106034.htmlis a rabbit polyclonal antibody, directed against mouse IL 1 beta. This antibody has been tested in staining paraffin embedded tissue sections. The application and species you wish to use are therefore covered by the Abpromise. The antibody is however biotin conjugated.

https://www.abcam.com/IL1-beta-antibody-HRP-ab106035.htmlis an HRP
conjugated rabbit polyclonal antibody and again has been tested in staining of paraffin embedded tissue sections. This would again be covered by the Abpromise for the application and speciesyou are looking to use. More information about the Abpromise can be found from the following link:


Alternatively, https://www.abcam.com/IL1-beta-antibody-ab9722.htmlis a quite well characterised rabbit polyclonal antibody directed against mouse IL 1 beta. This antibody has to our knowledge not been used in staining of paraffin embedded tissue yet. However this does not mean that it will not work, simply that we have not tested it so therefore do not know. As we are unable to guarantee such antibodies to work, we offer a testing discount scheme.

This offer means that if you purchase and test https://www.abcam.com/IL1-beta-antibody-ab9722.htmlin IHC on paraffin embedded sections and let us know of the results through an Abreview (no matter whether positive or negative) you would be eligible for a free primary antibody of your choice from our catalog. More information on this offer can be found from the following link:


If you would be interested in participating in this scheme please do let me know as a discount code needs to be issued prior to the purchase of https://www.abcam.com/IL1-beta-antibody-ab9722.html.

I hope this information has been of help. If you require any further information please do not hesitate to contact us again.
