  • Product overview

    Interferon alpha-1 in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Interferon alpha-1 protein in human serum, plasma, cell culture supernatants, and cell and tissue extracts.


    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. 


    Sensitivity:
    Samples in Sample Diluent NS: 1.1 pg/mL
    Samples in 1X Cell Extraction Buffer PTR: 1 pg/mL

  • Notes

    Interferon alpha-1 belongs to a group of functionally related but distinct proteins of interferon alpha family that share around 80% identity of their amino acid sequences. Members of the interferon-alpha family have both anti-viral and immunomodulatory activities on target cells.

  • SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.

  • The concentrations of Interferon alpha-1 were measured in duplicates, interpolated from the Interferon alpha-1 standard curves and corrected for sample dilution. Undiluted samples are as follows: plasma (EDTA) 100%, plasma (citrate) 100%, plasma (heparin) 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2).

  • The concentrations of Interferon alpha-1 were measured in duplicates, interpolated from the Interferon alpha-1 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 100%, cell culture media (RPMI1640 + 10% FBS) 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2).

  • The concentrations of Interferon alpha-1 were measured in duplicate and interpolated from the Interferon alpha-1 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Interferon alpha-1 concentration was determined to be 126 pg/mL in extract of HEK293T cells overexpressing Interferon alpha-1.

  • The concentrations of Interferon alpha-1 were measured in duplicate and interpolated from the Interferon alpha-1 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Interferon alpha-1 concentration was determined to be 427.9 pg/mL in 75 IU/mL WHO International Standard INTERFERON ALPHA (Human leukocyte-derived) NIBSC 94/784.

  • The concentrations of Interferon alpha-1 were measured in three different dilutions in duplicate and interpolated from the Interferon alpha-1 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted in ng Interferon alpha-1 per mg of extract (mean +/- SD, n=3). Interferon alpha-1 concentration was determined to be 647.6 ng/mg in extract of HEK293T cells overexpressing Interferon alpha-1. Values for the empty vector were below the minimum detectable dose.
