Quantification

In this sandwich ELISA, Human Interleukin 13,IL-13 ELISA KIT in the sample is captured between a pre-coated capture antibody and a detection antibody. Signal intensity is proportional to analyte concentration. Quantification uses a standard curve fitted with Curve Expert software, covering 3.12 pg/mL-200 pg/mL with a minimum detectable dose of 0.78 pg/mL.

For research use only (RUO). Not intended for diagnostic or therapeutic purposes. Validated in human serum, plasma, tissue homogenates, cell culture supernates matrices only.
Description

This ELISA kit provides quantitative measurement of interleukin-13 (IL-13) in human samples, supporting research into Th2-mediated immune responses, allergic inflammation, and tissue fibrosis. Because circulating IL-13 is typically present at low picogram-per-milliliter concentrations and rises modestly even during active disease, precise detection within a narrow dynamic window is essential for meaningful data.

Detection Range: The 3.12–200 pg/mL range aligns with reported IL-13 levels in human serum and plasma, which rarely exceed low double-digit pg/mL at baseline and may reach the tens-of-pg/mL range during allergic exacerbation or helminth infection. Most samples can be run neat or with minimal dilution, simplifying assay planning for clinical and translational studies.
