Function

Potent pro-inflammatory cytokine (PubMed:10653850, PubMed:12794819, PubMed:28331908, PubMed:3920526). Initially discovered as the major endogenous pyrogen, induces prostaglandin synthesis, neutrophil influx and activation, T-cell activation and cytokine production, B-cell activation and antibody production, and fibroblast proliferation and collagen production (PubMed:3920526). Promotes Th17 differentiation of T-cells. Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells (PubMed:10653850). Plays a role in angiogenesis by inducing VEGF production synergistically with TNF and IL6 (PubMed:12794819). Involved in transduction of inflammation downstream of pyroptosis: its mature form is specifically released in the extracellular milieu by passing through the gasdermin-D (GSDMD) pore (PubMed:33377178, PubMed:33883744). Acts as a sensor of S.pyogenes infection in skin: cleaved and activated by pyogenes SpeB protease, leading to an inflammatory response that prevents bacterial growth during invasive skin infection (PubMed:28331908).

Notes

Human IL-1 beta ELISA Kit ab214025 is a rapid single-wash 90-min ELISA kit to measure Human ALT in cell culture supernatant, serum, plasma. This SimpleStep ELISA® sensitivity is 5.64 pg/mL.

How the assay works

Human ALT SimpleStep ELISA® employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.

Assay Specificity

This kit recognizes both native and recombinant human ALT protein in serum, plasma, and cell culture supernatant samples only. Tissue extract samples have not been tested with this kit. This kit is incompatible with plasma- heparin and cell extract samples.

Human IL-1 beta ELISA Kit ab214025 protocol summary:

1. Mix: add samples/standards to the wells together with the capture and detector antibody cocktail. Incubate for 1 hr at room temperature
2. Wash
3. Add TMB development solution - incubate for 10 min
4. Add stop solution
5. Read the results on a plate reader at 450nm

Interleukin 1 beta (IL-1 beta) is produced by activated macrophages and 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.

    Interpolated concentrations of native IL-1beta in human PHA stimulated PBMC supernatant and LPS stimulated THP-1 supernatant samples.

    The concentrations of IL-1beta were measured in duplicates, interpolated from the IL-1beta standard curves and corrected for sample dilution. Undiluted samples are as follows: PBMC supernatant 50% and 100% THP-1 supernatant. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IL-1beta concentration was determined to be 1301 pg/mL in PBMC supernatant and 734 pg/mL in THP-1 supernatant.

    Sandwich ELISA - Human IL-1 beta ELISA Kit, Fluorescent (Human IL-1 beta ELISA Kit, Fluorescent ab229384).

    This data was collected using Human IL-1 beta ELISA Kit, Fluorescent ab229384, which uses the same recombinant antibody pair and standard protein. Human IL-1 beta concentration was interpolated from the standard curve. Supernatants from cell culture samples were serially diluted and assessed by the Human IL-1 beta ELISA kit (Human IL-1 beta ELISA Kit, Fluorescent ab229384). Wild-type and IL-1 beta knockout THP-1 cells (Human IL1B knockout THP-1 cell line ab273762) were assessed in duplicate (n=2). Cells were either treated with LPS (100 ng/ml, 3 h) then ATP (5 mM, 45 min) to induce expression of IL-1 beta or not treated. Data are represented as the mean and error bars represent standard deviation.
