IL-1β Antibody (B122) is a hamster monoclonal IgG antibody that detects IL-1β (B122) of mouse, rat, human, and hamster origin by western blotting (WB), immunoprecipitation (IP), and enzyme-linked immunosorbent assay (ELISA). IL-1β (B122) antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. IL-1β plays a pivotal role in the immune response and inflammation, acting as a key mediator that influences the activity of T and B lymphocytes as well as natural killer (NK) cells. Notably, IL-1β is produced in response to inflammatory stimuli and is crucial for the activation of immune cells, promoting the secretion of other cytokines such as IL-2 while inhibiting IL-4 expression in T cells. This regulatory function is essential for maintaining a balanced immune response, and dysregulation of IL-1β has been linked to various pathological conditions, including rheumatoid arthritis and inflammatory bowel disease. The ability of IL-1β to induce B cell proliferation and immunoglobulin synthesis further underscores its importance in adaptive immunity. By utilizing IL-1β (B122) antibody in research, you can gain valuable insights into the mechanisms of inflammation and immune regulation, contributing to a better understanding of both normal physiological processes and disease states.

For this antibody is there evidence of good cross-reactivity with Golden Syrian Hamsters. We want to use it in IHC against Hamster lungs.

Asked by: MaxR
Thank you for your question. We have not validated the antibody for Golden Syrian Hamster. The antibody is recommended for mouse, rat ,human and hamster samples.

Can I use an anti-mouse IgG secondary antiboby with this antibody made in Hamster?

Asked by: PaGar
Thank you for your question. We do not recommend using an anti-mouse IgG secondary antibody for detection of this primary antibody. IL-1β Antibody (B122) is a Armenian hamster monoclonal IgG, and so you will need to use a secondary antibody that is specific for the detection of Armenian hamster IgG. We recommend using our mouse anti-Armenian hamster IgG-HRP: sc-2789, for example, if you need the secondary antibody conjugated to HRP.

Can IL-1β (B122): sc-12742 monoclonal antibody be used in IF or IHC with mouse tissue or cells? Will there be non-specific staining?

Asked by: Cweed
Thank you for your inquiry. The use of mouse monoclonal antibodies with mouse samples is very common and typically poses no problem. To eliminate any potential cross-reactivity of an anti-mouse secondary detection reagent, IL-1β (B122): sc-12742 is available in a variety of direct conjugations, such as HRP, PE, FITC and AlexaFluors.

Rated 4 out of 5 by from Ab works goodAb were tested for direct ELISA to analyze the release level of IL-1beta from RAW 264.7 macrophage cell line. Tested conditions: 1:200 dilution in TBS-T overnight at 4°C and 1 h treatment with horseradish peroxidase-conjugated secondary antibody (1:1000 dilution). Measurements were carried out using TMB as a substrate (100 μl/well), reaction was stopped byaddition of 2N H2S04 (100 μl/well).
