  • 製品の概要

    IL-5 in vitro SimpleStep ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of IL-5 protein in human serum, plasma, cell culture supernatant and urine.


    The SimpleStep ELISA employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

  • 特記事項

    Interleukin 5 (IL-5) is a small, 113 amino acid cytokine produced by T cells involved in the differentiation of B-cells to immunoglobulin secreting cells. IL-5 is a key mediator in the survival and effector functions of mature eosinophils. Due to its effects on eosinophils, IL-5 is implicated in the pathogenesis of asthma and other hypereosinophilic inflammatory conditions.

  • Standard curve comparison between human IL-5 SimpleStep ELISA® kit and traditional ELISA kit from leading competitor. SimpleStep ELISA kit shows comparable sensitivity with shorter protocol time.
  • Background-subtracted data values (mean +/- SD) are graphed.

  • The concentrations of IL-5 were measured in duplicates, interpolated from the IL-5 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 50%, plasma (citrate) 50%, plasma (heparin) 50% and urine 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IL-5 concentration was determined to be 149 pg/mL in serum, 131 pg/mL in plasma (citrate), 165 pg/mL in plasma (heparin), 142 pg/mL in plasma (EDTA) and 133 pg/mL in urine.

  • Conditioned media was harvested after 48 hours. IL-5 was measured in 100% unstimulated and PHA stimulated PBMC supernatant. The concentrations of IL-5 were measured in duplicate, interpolated from the IL-5 standard curves and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IL-5 concentration was determined to be 226.9 pg/mL in PHA stimulated PBMC supernatant and 1.94 pg/mL in unstimulated PBMC supernatant.
