Interpolated concentrations of native IL-19 in human urine (25%), samples.

The concentrations of IL-19 was measured in duplicate and interpolated from the IL-19 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IL-19 concentration was determined to be 91.95 pg/mL in urine.

Interpolated concentrations of native IL-19 in human milk (0.5%), saliva (10%), and PBMC supernatant (50%) samples.

The concentrations of IL-19 were measured in duplicate and interpolated from the IL-19 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean IL-19 concentration was determined to be 37.14 ng/mL in milk, 91.95 pg/mL in urine, 779.30 pg/mL in saliva, and 1008.97 pg/mL in PBMC supernatant.

Product details

Human IL-19 ELISA Kit (ab231922) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of IL-19 protein in cit plasma, edta plasma, hep plasma, milk, saliva, serum, urine, and cell culture supernatant. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human IL-19 with 0.648 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.

Target data

Cytokine that functions as an anti-inflammatory and proangiogenic factor (PubMed : 34932373). Polarizes adaptive immunity to an anti-inflammatory phenotype through induction of T-helper 2 responses by both down-regulation of IFN-gamma and up-regulation of IL4 and IL13 (PubMed : 16365913). Produced by osteocytes, stimulates granulopoiesis and neutrophil formation (By similarity). Exerts its biological effect through a receptor complex consisting of a heterodimer of IL20RA and IL20RB (PubMed : 12351624). In turn, activates the Janus kinase (JAK) and signal transducer and activator of transcription (STAT) pathway, and importantly, STAT3 (PubMed : 11564763).
