- 实验流程
- human IL-1 beta ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for IL-1 beta has been precoated onto 96-well plates. Standards (E.coli,A117-S269) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for IL-1 beta is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human IL-1 beta amount of sample captured in plate.

Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of human cell culture supernatants, serum or plasma(heparin, EDTA, citrate) to each empty well. See "Sample Dilution Guideline" above for details. We recommend that each human IL-1 betastandard solution and each sample is measured in duplicate.

- Plasma from LPS stimulated human whole blood; Recombinant human IL-1B with increasing concentrations of canakinumab.

- Performed following the instructions provided by the manufacturer.
- Notes
Passed. ABIN411293 detects IL-1B in plasma from human whole blood. In the presence of increasing concentrations of canakinumab, false low IL-1B concentrations were detected, limiting the kit’s practicability.

- Full Protocol
- Collect blood from volunteers in hirudin coated tubes (Sarstedt, 04.1944.001).
- Distribute blood samples on 96 well plates using 140µl per well.
- Add ultra-pure LPS (Invivogen, tlrl-3pelps) to each well to a concentration of 1µg/ml to primer samples for NLRP3 assays.
- Incubate plates on a shaker (450rpm) in a humidified incubator for 5.5h at 37°C and 5% CO2.
- For NLRP3 inflammasome activation, add ATP (Invivogen, tlrl-atpl) to each well to a concentration of 1mM.
- Incubate plates on a shaker (450rpm) in a humidified incubator for 30min at 37°C and 5% CO2.
- Add 100µl PBS to each well.
- Centrifuge plates for 5min at 1200rpm at RT and freeze the supernatant from each well at -80°C.
- For analysis of canakinumab interference with ABIN411293, dilute recombinant IL-1B (BD, 558457) to 800pg/ml in RPMI1640 and incubate it with increasing doses of canakinumab (0µg/ml, 0.0001µg/ml, 0.001µg/ml, 0.01µg/ml, 0.1µg/ml, 1µg/ml, 10µg/ml, 100µg/ml) for 2h at RT.
- Perform measurements according to the manufacturer’s protocol.
- Analyze standards and samples in duplicate. Use assay buffer as blank and subtract the mean blank was subtracted from all raw data reads.
- Use a five parameter logisitic curve to calculate the standard curve.
- Experimental Notes
The aim was to analyze the ability of ABIN411293 to detect IL-1B in plasma from stimulated human whole blood and in the presence of the therapeutic IL-1B antibody canakinumab.
Analysis of stimulated human whole blood showed the expected results, therefore ABIN411293 is suitable to detect IL-1B from plasma of stimulated human whole blood. Of note, increasing doses of canakinumab seem to interfere with the binding of the ELISAs antibodies leading to detection of false low IL-1B concentrations. Therefore, the ELISA may not be used to analyze serum or plasma from patients receiving therapeutic canakinumab.

- 背景
-
Protein Function: Produced by activated macrophages, IL-1 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. .
Background: Interleukin-1beta(IL-1beta) is a potent stimulator of bone resorption whose gene is mapped to 2q14, and has been implicated in the pathogenesis of high bone turnover and osteoporosis. IL-1beta, a prominent microglia-derived cytokine, caused oligodendrocyte death in coculture with astrocytes and microglia, but not in pure culture of oligodendrocytes alone. It also can cause nuclear export of a specific NCOR corepressor complex, resulting in derepression of a specific subset of nuclear factor-kappa-B(NFKB)-regulated genes. Furthermore, Microenvironmental IL-1beta and, to a lesser extent, IL-1alpha are required for in vivo angiogenesis and invasiveness of different tumor cells. Additional, the cooperation of IL-1beta and PDGFB induces contractile-to-synthetic phenotype modulation of human aortic smooth muscle cells in culture. Moreover, the association with disease may be explained by the biologic properties of IL-1beta, which is an important proinflammatory cytokine and a powerful inhibitor of gastric acid secretion.
Synonyms: Interleukin-1 beta,IL-1 beta,Catabolin,IL1B,IL1F2,
Full Gene Name: Interleukin-1 beta
Cellular Localisation: Secreted. The lack of a specific hydrophobic segment in the precursor sequence suggests that IL-1 is released by damaged cells or is secreted by a mechanism differing from that used for other secretory proteins. - 基因ID
