  • 製品の概要

    Abcam’s Human IL-1RA ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human IL-1RA in cell lysates and tissue lysates.

    This assay employs an antibody specific for Human IL-1RA coated on a 96-well plate. Standards and samples are pipetted into the wells and IL-1RA present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human IL-1RA antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of IL-1RA bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • 機能Inhibits the activity of interleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP for signaling. Has no interleukin-1 like activity. Binds functional interleukin-1 receptor IL1R1 with greater affinity than decoy receptor IL1R2; however, the physiological relevance of the latter association is unsure.
  • 組織特異性The intracellular form of IL1RN is predominantly expressed in epithelial cells.
  • 関連疾患Genetic variation in IL1RN is associated with susceptibility to microvascular complications of diabetes type 4 (MVCD4) [MIM:612628]. These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis.
    Defects in IL1RN are the cause of interleukin 1 receptor antagonist deficiency (DIRA) [MIM:612852]; also known as deficiency of interleukin 1 receptor antagonist. Autoinflammatory diseases manifest inflammation without evidence of infection, high-titer autoantibodies, or autoreactive T-cells. DIRA is a rare, autosomal recessive, genetic autoinflammatory disease that results in sterile multifocal osteomyelitis (bone inflammation in multiple places), periostitis (inflammation of the membrane surrounding the bones), and pustulosis (due to skin inflammation) from birth.

  • IL-1Ra measured in RIPA lysates from control cells (-) or cells stimulated for 24 hours with 50 ng x mL-1 of PMA (ab120297) with the addition of 1 ug x mL-1 of LPS (Sigma) (P/L) for the last 6 hours (IL-1Ra per million cells; duplicates +/- SD). 5e6 cells were lysed in 0.1 mL, and tested in the dilution range of 1/1-1/40.  

  • IL-1Ra measured in culture supernatants from control (-) or activated PBMCs ((PHA) 48 hours with 2% PHA-M; LifeTechnologies) and in human biological fluids. Signals from plasma and serum were below level of detection (duplicates +/- SD).

  • Standard curve with background signal subtracted (duplicates; +/- SD).

  • Representative standard curve using ab100565

Thank you for contacting us.
Thank you for your inquiry. Unfortunately we have not tested this kit for cross reactivity with rat. If it helps, the capture antibody used is monoclonal and the detection antibody is polyclonal. If you do wish to test...
