Product overview
Rat IL-17A ELISA Kit (ab214028) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of IL-17A protein in cell culture supernatant, cit plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Rat IL-17A with 1.1 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
INTERFERENCE
Recombinant mouse IL-17F was prepared at 50 ng/mL and 1 ng/mL and tested for interference. No interference with was observed.
SPECIES REACTIVITY
This kit recognizes rat IL-17A protein. It also reacts with mouse IL-17A protein.
Mouse and human species reactivity was determined by measuring 2-fold dilutions of mouse and human recombinant IL-17A protein (see below). Other species reactivity was not determined.

Notes
IL-17A is a pro-inflammatory cytokine that is secreted by a subset of activated T cells. It is a disulfide-linked homodimer with both glycosylated and non-glycosylated forms. IL-17A induces stromal cells to produce pro-inflammatory and hematopoietic cytokines, and also enhances the surface expression of ICAM1/intracellular adhesion molecule 1 in fibroblasts.

Comparison of IL-17a in unstimulated and Concanavalin A stimulated rat spleen cell supernatants.Rat spleen cells were cultured in the absence or presence of 5 µg/mL Concanavalin A for 48 hours. The concentrations of Il-17a were measured in neat supernatant samples in duplicates and interpolated from the IL-17a standard curve. The interpolated values are plotted (mean +/- SD, n=2). The mean IL‑17a concentration was determined to be 33.2 pg/mL in unstimulated, 187 pg/mL in Concanavalin A stimulated supernatants and undetectable in media (not shown).

Interpolated concentrations of native IL-17a in 2 days 5 µg/mL Concanavalin A treated rat spleen cell culture supernatant samples.The concentrations of IL-17a were measured in duplicates, interpolated from the IL-17a standard curves and corrected for sample dilution. Undiluted samples are as follows: rat spleen cell culture supernatant 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IL-17a concentration was determined to be 190 pg/mL in Concanavalin A treated rat spleen cell culture supernatant.

Serial dilutions of recombinant rat IL-17a homodimer, recombinant mouse IL-17f homodimer and recombinant mouse IL-17a/f heterodimer were measured with this kit.Background-subtracted data values (n = 1) are graphed. Note that this kit is specific for IL-17a homodimer, it does not recognize IL-17f homodimer or IL-17a/f heterodimer.
-
Titration of mouse, rat and human recombinant IL-17a within the working range of the assay.Two fold serial dilutions of rat, mouse and human recombinant IL-17a proteins were measured with this kit. Background-subtracted data values (mean +/- SD, n = 2) are graphed. O.D. values for human IL-17a protein were below background values. Note this kit reacts with mouse recombinant IL-17a protein. Note this kit does not react with human recombinant IL-17a protein.

Linearity of dilution.Linearity of dilution is determined based on interpolated values from the standard curve. Linearity of dilution defines a sample concentration interval in which interpolated target concentrations are directly proportional to sample dilution.
Recombinant IL-17A was spiked into the following biological samples and diluted in a 2-fold dilution series in Sample Diluent 75BS.
100% pooled serum and plasma (citrate) samples from healthy donors was measured in duplicate. All values were below the detectable range of the assay.

Linearity of dilution.Linearity of dilution is determined based on interpolated values from the standard curve. Linearity of dilution defines a sample concentration interval in which interpolated target concentrations are directly proportional to sample dilution.
Native IL-17A was measured in the following biological samples in a 2-fold dilution series. Sample dilutions are made in Sample Diluent NS.
-
Assay sensitivity.The MDD was determined by calculating the mean of zero standard replicates and adding 2 standard deviations then extrapolating the corresponding concentration.
