This antibody was prepared by repeated immunizations with recombinant mouse IL-1 beta/IL-1F2 produced in E.coli. The MW of recombinant mouse IL-1 beta was 17 kDa.
This antibody is primarily directed against mature, 17,000 MW mouse IL-1 beta and is useful in determining its presence in various assays. The antibody does not recognize human IL-1 beta or mouse IL-1a. In ELISA formats and other immunoreactive assays, reactivity occurs with rat IL-1 beta. This antibody will recognize 10% of the non-denatured (native) precursor 31,000 MW mouse IL-1 beta containing samples but will primarily detect all of the 17,000 MW mature molecule. However, in immunoblot analysis, the usual procedure of heating the sample in SDS with or without reducing agents will facilitate denaturing of the 31,000 MW IL- 1 beta precursor molecule. Denatured 31,000 precursor IL-1 beta will be recognized by this antibody.

This antibody 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 are stimulated for 24 hours with 1% serum plus 10 ng/mL E.coli LPS. For immunoprecipitation pre-clearing the preparation with a non-specific Rabbit IgG - reduce background is suggested. For immunohistochemistry either paraffin fixation or cryofixation can be used for sample preparation - stain intracellular IL-1Beta. For ELISA use HRP Conjugated Anti-Rabbit IgG [H&L] 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 mouse and rat IL-1Beta activity in bioassays. It does not neutralize the biological activity IL-1alpha. It does not neutralize the biological activity of human or primate IL-1Beta. For neutralization, it is recommended - 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 f. Caution should be exhibited as the F domain of the rabbit IgG molecule may interact with cells non-specifically.Flow Cytometry was reported in scientific literature.

Alternate Names for IL-1 beta/IL-1F2 Antibody [Biotin]
interleukin 1, beta
preinterleukin 1 beta
IL-1 beta (also known as Interleukin-1 beta, IL-1beta and catabolin) is produced by activated macrophages. IL-1 stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1 proteins are involved in the inflammatory response, being identified as endogenous pyrogens, and are reported to stimulate the release of prostaglandin and collagenase from synovial cells. IL-1beta is a monomeric secreted protein that may be released by damaged cells or is secreted by a mechanism differing from that used for other secretory proteins.

Single cell suspension was blocked with Fc block for 30 minutes, prior to the permeabilization with BD cytoperm/fix kit for an additional of 30 minutes. Cells were then washed and incubated with the biotinylated-conjugated IL1b antibody (1:100 in PERM buffer) for 30 minutes on ice. Cells were then briefly washed and analyzed by flow cytometry.
