Description | This is an IgG preparation of whole rabbit serum purified by DEAE fractionation. Store vial at -20C prior to opening. Aliquot contents and freeze at -20C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use. |
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) |
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). |

IL-1 beta (interleukin 1 beta, lymphocyte activating factor (LAF)) IL-1 was originally identified and cloned as a lymphocyte mitogen and much later, was found to be comprised of two closely related but distinct proteins, interleukin 1 alpha (IL-1 alpha) and interleukin 1 beta (IL-1 beta). Both these proteins bind ... Read full blog post. |
