IL-1 beta Antibody (YA345)

IL-1 beta Antibody (YA345) is a Rabbit-derived and non-conjugated IgG monoclonal antibody, targeting to IL-1 beta.

IL-1 beta Protein stands as a potent pro-inflammatory cytokine, recognized for its diverse roles in orchestrating immune responses. Originally identified as a major endogenous pyrogen, IL-1 beta induces a cascade of inflammatory events, including prostaglandin synthesis, neutrophil influx and activation, T-cell and B-cell activation, cytokine production, as well as fibroblast proliferation and collagen production. It plays a pivotal role in immune cell differentiation, promoting Th17 differentiation of T-cells and synergizing with IL-12 to induce IFNG synthesis from T-helper 1 (Th1) cells. Additionally, IL-1 beta contributes to angiogenesis by inducing VEGF production, working synergistically with TNF and IL-6. Notably, it plays a key role in transducing inflammation downstream of pyroptosis, being specifically released into the extracellular milieu through the gasdermin-D (GSDMD) pore. In the context of microbial infection, IL-1 beta acts as a sensor of S. pyogenes infection in the skin, undergoing cleavage and activation by the pyogenes SpeB protease, leading to an inflammatory response that curtails bacterial growth during invasive skin infection. However, the cleavage of IL-1 beta by SpeB has a dual role, promoting streptococcal infection of the nasopharynx by disrupting colonization resistance mediated by the microbiota.

• 
  Western blot analysis of extracts from THP-1 (lane 2(20μg) and THP-1 (lane 3(20μg) , LPS treated (HY-D1056, 100ng/mL, 2hrs) as indicated, using IL-1 beta(HY-P80503) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
• 
  Immunohistochemical analysis of paraffin-embedded Mouse spleen tissue using IL-1 beta Antibody (YA345). The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HY-P80503, 1/100) in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
