Function
The Interleukin 1 (IL-1) family of proteins consists of IL-1 alpha, IL-1 beta, and the IL-1 receptor antagonist (IL-1ra). IL-1 alpha and IL-1 beta bind to the same cell surface receptors and share biological functions. IL-1 is not produced by unstimulated cells of healthy individuals with the exception of skin keratinocytes, some epithelial cells, and certain cells of the central nervous system. However, in response to inflammatory agents, infections, or microbial endotoxins, a dramatic increase in the production of IL-1 by macrophages and various other cell types is seen. IL-1 beta plays a central role in immune and inflammatory responses, bone remodeling, fever, carbohydrate metabolism, and GH/IGF-I physiology. Inappropriate or prolonged production of IL-1 has been implicated in a variety of pathological conditions including sepsis, rheumatoid arthritis, inflammatory bowel disease, acute and chronic myelogenous leukemia, insulindependent diabetes mellitus, atherosclerosis, neuronal injury, and aging-related diseases. IL-1 alpha and IL-1 beta are structurally related polypeptides that show approximately 25% homology at the amino acid (aa) level. Both are synthesized as 31 kDa precursors that are subsequently cleaved into mature proteins of approximately 17.5 kDa. Cleavage of the IL-1 beta precursor by Caspase-1/ICE is a key step in the inflammatory response. Neither IL-1 alpha nor IL-1 beta contains a typical hydrophobic signal peptide, but evidence suggests that these factors can be secreted by non-classical pathways. A portion of unprocessed IL-1 alpha can be presented on the cell membrane and may retain biological activity. The precursor form of IL-1 beta, unlike the IL-1 alpha precursor, shows little or no biological activity in comparison to the processed form. Both unprocessed and mature forms of IL-1 beta are exported from the cell.

Indirect ELISA analysis of Mouse IL-1 beta was performed by coating wells of a 96-well plate with 50 µL per well of Mouse IL-1 beta-BSA diluted in carbonate/bicarbonate buffer, at a concentration of 1 µg/mL overnight at 4℃. Wells of the plate were washed, blocked with 1%BSA blocking buffer for 1 hour at 37℃, and incubated with 50 µL per well of Mouse IL-1 beta monoclonal antibody serial diluted starting from a concentration of 1µg/mL for 45 minutes at 37℃. The plate was washed and incubated with 50 µL per well of an HRP-conjugated goat anti-rabbit IgG secondary antibody at a dilution of 1/80,000 for 30 minutes at 37℃. Detection was performed using an Ultra TMB Substrate for 10 minutes at 37℃ in the dark. The reaction was stopped with sulfuric acid and absorbances were read on a spectrophotometer at 450 nm.
