Product Specifications

Immunogen

This IL-1 beta/IL-1F2 Antibody was prepared by repeated immunizations with recombinant human IL-1 beta/IL-1F2 produced in E.coli. The MW of the recombinant 153 aa IL-1 beta/IL-1F2 was 17 kDa with the N-terminal amino acid at position alanine 117. This cleavage site is generated by the IL-1 beta/IL-1F2 converting enzyme (ICE, capase-1). (Uniprot: P01584)

Reactivity Notes

In general, this antibody also detects primate IL-1 beta/IL-1F2 in the same formats using similar dilutions. Use in Mouse reported in scientific literature (PMID: 33731931).

Localization

Secreted

Specificity

This antibody is primarily directed against mature, 17,000 MW human IL-1 beta/IL-1F2and is useful in determining its presence in various assays. In general, this antibody also detects primate IL-1 beta/IL-1F2in the same formats using similar dilutions. The antiserum does not recognize human IL-1alpha. In ELISA formats and other immunoreactive assays, this antibody will recognize 10% of the non-denatured (native) precursor 31,000 MW IL-1 beta/IL-1F2containing samples but will primarily detect all of the 17,000 MW mature molecule. However, in immunoblot analysis of natural cell products or human body fluids, the usual procedure of hearing the sample in SDS with or without reducing agents will facilitate denaturing of the 31,000 MW IL- 1beta precursor molecule. Denatured 31,000 precursor IL-1 beta/IL-1F2will be recognized by this antibody but often migrates as a 35,000 MW band. This is due to the unfolding of the denatured precursor IL-1 beta/IL-1F2exposing epitopes not exposed in the natural state. In immunoblots, depending on the number of cells, the antibody detects the 17,000 MW band in supernatants as well as a 35,000 MW band representing the 31,000 MW IL-1 beta/IL-1F2precursor in lysates.

Application Notes

This product has been tested for use in ELISA, immunohistochemistry, immunoblotting. This antibody is suitable for neutralizations, radioimmunoassays, flow cytometry, and immunoprecipitation. It recognizes the 17,000 MW mature IL-1beta. For immunoblots, typically, IL-1beta is detected from supernatants or lysates of 2 x 10E6 endotoxin-stimulated peripheral blood mononuclear cells (PBMC). PBMC are stimulated for 24 hours with 1% (v/v) serum plus 10 ng/mL E.coli LPS. For immunoprecipitation pre-clearing the preparation with a non-specific Rabbit IgG to reduce background is suggested. For immunohistochemistry either paraffin fixation or cryofixation can be used for sample preparation to stain intracellular IL-1beta. For ELISA use HRP Conjugated Anti-Rabbit IgG [H&L] (Goat) (611-1302) for detection. In ELISA formats this antibody is best used as the second antibody in combination with a monoclonal antibody as a capture antibody. This antibody is also useful for neutralization of human and primate IL-1beta activity in bioassays. It does not neutralize the biological activity IL-1alpha. It does not neutralize the biological activity of murine, rat or rabbit IL-1beta. For neutralization, it is recommended to incubate the sample with a dilution of the antibody for at least 4 hours before being tested. A control of similarly diluted normal rabbit IgG is recommended. This antibody can be used for FACS analysis. Caution should be exhibited as the F(c) domain of the rabbit IgG molecule may interact with cells non-specifically.

Use in Immunohistochemistry-Frozen reported in scientific literature (PMID: 22898394).

Use in Immunohistochemistry Whole-Mount reported in scientific literature (PMID:31399621).

Background: IL-1 beta/IL-1F2

Interleukin-1 beta (IL-1 beta), also called IL-1F2, is a proinflammatory cytokine that functions in host defense following injury or inflammation (1-5). IL-1 beta is expressed by cells of the immune system such as monocytes, macrophage, neutrophils, and hepatocytes (1-3). Human IL-1 beta protein is expressed in the cytoplasm in an inactive precursor form (pro-IL-1 beta) which is 269 amino acids in length with a theoretical molecular weight of 31 kDa (1,4,6). Pro-IL-1 beta is cleaved by IL-1 converting enzyme (ICE), also called caspase-1, generating the 18 kDa mature, active protein that is secreted from cells (1,4,6). Pro-IL-1 beta is produced as a cellular response to molecular signals from pathogens and other processes termed pathogen associated molecular patterns (PAMPs) and damage associated molecular patterns (DAMPs) (1,2). PAMPs and DAMPs signal through pattern recognition receptors (PRRs) to induce formation of the inflammasome (1,2). The inflammasome is a multi-protein complex made of a PRR, such as Nod-like receptor family, pyrin domain containing 3(NLRP3), an adaptor, such as apoptosis-associated spec-like protein containing a CARD (ASC), and pro-caspase-1 (1-3,5). Assembly of the inflammasome enables cleavage of pro-caspase-1 into active caspase 1, followed by secretion of activate IL-1 beta (1-3,5).

IL-1 beta binding to its receptor IL-1RI and the downstream signaling contributes to a dual pathophysiological role (3). On one hand, IL-1 beta signaling activates immune cells and drives CD4+ T cell polarization to T helper type 1 (Th1) and Th17 cells, resulting in anti-tumor responses and mediation of acute inflammation (2,3). However, IL-1 beta also supports tumor growth and metastasis driven by multiple mechanisms including chronic inflammation, an immunosuppressive tumor microenvironment (TME), and angiogenesis (3). Additionally, IL-1 beta signaling been implicated in the pathogenesis of neuroinflammatory diseases of the central nervous system (CNS) such as multiple sclerosis (MS), Alzheimer's disease, and diabetic retinopathy (DR) (2). Mouse studies have shown regression of tumors treated with IL-1 as well as protective effects of IL-1 beta in instances of induced colitis and colon carcinoma (3). Conversely, blocking IL-1 beta has also shown promising effect in cancer treatment, especially when combined with chemotherapeutics (2,3). Approved IL-1 beta monoclonal antibody canakinumab has shown significant therapeutic promise in the treatment of DR (2). Given its multifaceted role in disease, IL-1 beta is a promising therapeutic target.
