产品详细信息Description: The CRM56 antibody reacts with human and baboon interleukin-1 beta; (IL-1 beta). IL-1 beta is a 17 kDa factor secreted primarily by monocytes. IL-1 has effects on T-helper cells, inducing IL-2 secretion and expression of IL-2 receptors. IL-1 has effects on B cells, promoting cell proliferation and immunoglobulin synthesis.Applications Reported: The CRM56 antibody has been reported for use in intracellular staining for flow cytometric analysis, cytokine neutralization, and ELISA. Fluorochrome conjugated CRM56 is recommended for use in intracellular staining for flow cytometry. Functional Grade purified CRM56 (cat. 16-7018) is recommended for use in functional assays.Applications Tested: The CRM56 antibody has been tested as the capture antibody in a sandwich ELISA for analysis of human interleukin-1 beta (IL-1 beta) in combination with the biotin CRM57 (13-7016) antibody for detection and recombinant human IL-1 beta (14-8018) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 1 - 4 µg/mL. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 1000 pg/mL - 8 pg/mL should be included in each ELISA plate.The Functional Grade Purified CRM56 antibody has been tested for neutralization of IL-1 beta bioactivity.Purity: Greater than 90%, as determined by SDS-PAGE.Aggregation: Less than 10%, as determined by HPLC.Filtration: 0.2 µm post-manufacturing filtered.靶标信息Interleukin-1 beta (IL-1 beta) is a proinflammatory cytokine expressed by monocytes, macrophages, and dendritic cells. IL-1 beta is synthesized in response to inflammatory stimuli as a 31 kDa inactive pro-form that accumulates in the cytosol. Cleavage of pro-IL-1 beta into the active 17 kDa protein requires the activation of inflammasomes, which are multi-protein complexes that respond to pathogens, stress conditions, and other danger signals. Inflammasome activation triggers the processing of the caspase-1 precursor into its active form, which in turn cleaves pro-IL-1 beta. IL-1 beta lacks a signal sequence peptide for classical ER/Golgi pathway and is secreted alongside caspase-1 via an alternate and incompletely understood mechanism. Although IL-1 beta is most often secreted in its active form, secretion of the uncleaved protein may be detectable under some biological conditions. IL-1 beta signals through two receptors, IL-1RI and IL-1RII, both of which are shared with IL-1 alpha. IL-1 beta activity can be moderated by IL-1 Receptor Antagonist (IL-1RA), a protein produced by many cell types that blocks receptor binding through competitive inhibition. IL-1 beta play an important role in innate host defense by triggering the production of other proinflammatory cytokines in target cells and initiating acute-phase responses to infection and injury. Elevated levels of IL-1 beta have been associated with many chronic inflammatory conditions IL-1 beta neutralizing antibodies potential therapeutic value.

IL-1 beta Antibody (14-7018-81) in FlowStaining of human peripheral blood mononuclear cells stimulated with LPS in the presence of Brefeldin A for 4 hours with Anti-Human CD14 PE (Product # 12-0149-42) (left) or Anti-Human CD14 FITC (Product # 11-0149-42) (right) followed by intracellularly Anti-Human IL-1 beta PE. IL-1 beta Antibody (14-7018-81)Oncotarget 2015 -Figure 7 Induction of EMT after CPT treatment of SKOV3 cells A. RT-qPCR expression analysis of the indicated EMT marker genes after the indicated times of CPT treatment (sample size: n >= 3). B. Flow cytometry analysis of intracellular SMA after 0, 2 or 21 weeks of CPT treatment (sample size: n = 3). Values represent the fold change (FC) in the number of positive cells relative to small cells on day 0 (normalized to 1). Cells gated for small cells (forward and sideward scatter as untreated SKOV3 cells) and larger cells (forward and sideward scatter larger than for SKOV3 cells). C. Flow cytometry analysis of IL-1beta expression in SMA-expressing SKOV3-R cells gated as in panel B. D. Labeling of actin filaments with California Red-conjugated phalloidin (red) after different periods of CPT exposure. E. Additional staining of the tight junction (zonula occludens) protein constituent ZO-1 by indirect immunofluorescence (green) in untreated SKOV3 and SKOV3-R cells. Nuclei were stained with DAPI in panels D and E. F. RT-qPCR analysis of VIM expression in SKOV3-R cells (21w) and the same cells grown in the absence of CPT for 7 days. G. Pro-inflammatory and EMT marker gene expression after cyclic CPT treatment (1 day CPT, 21 days recovery, 4 cycles) compared to untreated cells (sample size: n = 3).
