QC145 , Quantikine Immunoassay Control Set 617 Human Pro-IL-1 beta -
The Quantikine Human Pro-IL-1 beta is a sandwich enzyme-linked immunoassay. The capture antibody coated to the microplate is specific for the pro-piece of the molecule (first 116 residues), and the detection antibody is specific for mature IL-1 beta. Thus, the assay does not detect either the pro-piece alone or the mature form alone; it is specific instead for the intact pro-IL-1 beta.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision
Cell Culture Supernates
Serum, EDTA Plasma, Heparin Plasma
The recovery of pro-IL-1 beta spiked to three different levels throughout the assay in various matrices was evaluated.

To assess the linearity of the assay, five samples spiked with high concentrations of pro-IL-1 beta were diluted in the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: IL-1 beta/IL-1F2
IL-1 beta (Interleukin-1 beta) is produced in response to inflammatory agents, infections, or microbial endotoxins. It plays a central role in immune and inflammatory responses, bone remodeling, fever, carbohydrate metabolism, and GH/IGF-I physiology. IL-1 beta dysregulation is implicated in many pathological conditions including sepsis, rheumatoid arthritis, inflammatory bowel disease, acute and chronic myelogenous leukemia, insulin-dependent diabetes mellitus, atherosclerosis, neuronal injury, and aging-related diseases. Intracellular cleavage of the IL-1 beta precursor by Caspase-1/ICE is a key step in the inflammatory response. IL-1 beta binds to IL-1 RI and IL-1 RII. The IL-1 receptor accessory protein (IL-1 RAcP) associates with IL-1 RI and is required for IL-1 RI signal transduction, and IL-1ra is a secreted molecule that functions as a competitive inhibitor of IL-1 bioactivity.
Refer to the product for complete assay procedure.
Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
Prepare all reagents, standard dilutions, and samples as directed in the product insert.
Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
