Materials Required But Not Provided
- Microplate reader in standard size.

- Adjustable pipettes and pipette tips. Multichannel pipettes are recommended in the condition of large amount of samples in the detection.
- Clean tubes and Eppendorf tubes.
- Washing buffer (neutral PBS or TBS).
- Preparation of 0.01M TBS: Add 1.2g Tris, 8.5g NaCl; 450μl of purified acetic acid or 700μl of concentrated hydrochloric acid to 1000ml H2
- Preparation of 0.01 M PBS: Add 8.5g sodium chloride, 1.4g Na O and adjust pH to 7.2-7.
Typical Data Obtained from Human IL-1 Beta PicoKine™ ELISA Kit
(TMB reaction incubate at 37°C for 15-20min)
Intra/Inter Assay Precision

Three samples with differing target protein concentrations were assayed using four different lots to measure the CV% lot to lot variance.
To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.

*The typical data is obtained from Boster's internal QC result and for reference only. It may differ from the lab test results of the end users. It is more important that the user's lab test results reflect the same linearity demonstrated in the typical data than achieving exactly the same O.D. values.

|Alternative Names||Interleukin-1 beta;IL-1 beta;Catabolin;IL1B;IL1F2;|
|Subcellular Localization||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.|

*if product is indicated to react with multiple species, protein info is based on the human gene.
|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.|

"User Friendly And Economical ELISA Kit"
--Dhruva Bhattacharya, University of Arizona, Opthalmology and Vision Science, Postdoctoral Research Associate
Application ELISA Sample "Culture media supernatant" of transformed cultured cells of human conjunctiva epithelial cells Detection --
"I am very much satisfied with the product Human IL-1 Beta PicoKine™ ELISA Kit (EK0392) purchased from Boster Bio. I used the Boster Bio ElISA kit for the first time and I am very happy with this product. After trying the IL-1beta kit, I have purchased two other cytokine detection ELISA kits from Boster Bio. The methodology of Human IL-1 Beta PicoKine™ ELISA Kit is simplified and user friendly. It required minimum optimization for my experiments. The written instructions provided with the kit is very useful for running the ELISA. The results obtained so far have been consistent and reproducible. For my future ELISA experiments, I'll be buying the ELISA kit from Boster Bio."

"Good quality budget option"
--Milos Lazic, JECURE THERAPEUTICS, SCIENTIST II
Applications ELISA Sample protein concentrations in cell culture media Detection --
"We are a pharmaceutical startup optimizing cell based drug assays where one of our endpoints was observing the differences in mature IL-1b production in the media. I have compared several kits from the most expensive versions of R&D, over eBioscience/Affymetrix to a more budget Boster's kit. The aim was to decide what is the best price for the value and quality we are getting for reliable and replicable ELISA analyses. This assay was used to test the effect of increasing concentrations of a drug on IL-1b levels (dose response). The kit reported similar data obtained from the other two kits (R&D and eBiosciences), with a slightly larger standard deviations. Results replicated the findings of the previous kits and the assay had good sensitivity/ instructions on how to perform assay and analyze data. I would use this assay in an academic lab for a project where no more than 2-3 96-well plates will be used. It should be done carefully by a scientist that has previously performed ELISA assays. There are many steps to it. It is a good quality budget option to the other leading kits on the market. I would not recommend it for a larger drug screen assay where more than 5 ELISAs kits ought to be used."
The 1XTBS can be used if the pH value falls in the range of 7.2-7.6.
