Function

The protein encoded by this gene is a member of the interleukin 1 cytokine family. This protein inhibits the activities of interleukin 1, alpha (IL1A) and interleukin 1, beta (IL1B), and modulates a variety of interleukin 1 related immune and inflammatory responses, particularly in the acute phase of infection and inflammation. This gene and five other closely related cytokine genes form a gene cluster spanning approximately 400 kb on chromosome 2. A polymorphism of this gene is reported to be associated with increased risk of osteoporotic fractures and gastric cancer. Several alternatively spliced transcript variants encoding distinct isoforms have been reported. Anti-inflammatory antagonist of interleukin-1 family of proinflammatory cytokines such as interleukin-1beta/IL1B and interleukin-1alpha/IL1A. Protects from immune dysregulation and uncontrolled systemic inflammation triggered by IL1 for a range of innate stimulatory agents such as pathogens.

  • Sandwich ELISA analysis of human IL-1RA matched pair antibodies<br /><br />Elisa assay was performed by coating wells of a 96-well plate with 100 µl per well of capture antibody (<a href="/products/HA722788" style="font-weight: bold;text-decoration: underline;">HA722788</a>) diluted in carbonate/bicarbonate buffer, at a concentration of 2 µg/ml overnight at 4℃. Wells of the plate were washed, blocked with 150 µl 0.05% tween-20 1%BSA blocking buffer, and incubated with serial diluted Recombinant human IL-1RA protein (<a href="/products/HA210837" style="font-weight: bold;text-decoration: underline;">HA210837</a>) starting from 2000 pg/ml to 0 pg/ml and detect antibody (<a href="/products/HA722790B" style="font-weight: bold;text-decoration: underline;">HA722790B</a>, 0.2 µg/ml) for 1 hour at 30℃ with shaking. Then the plate was washed and incubated with 100 µl per well of SA-HRP for 0.5 hour at 30℃ with shaking. Detection was performed using an Ultra TMB Substrate for 10 minutes at room temperature in the dark. The reaction was stopped with sulfuric acid and absorbances were read on a spectrophotometer at 450 nm.

  • Interpolated concentrations of native IL-1RA in human samples.<br /><br />Interpolated concentration of native IL-1RA was measured in duplicate at different sample concentrations and interpolated from the IL-1RA standard curves. Undiluted samples were 50% samples. The interpolated dilution factor corrected values were plotted (mean +/- SD, n=2). The mean IL-1RA concentration was determined to be 4983 pg/mL in human urine.
