Intra-assay Precision (Precision within an assay): CV%<8% | ||||||
Three samples of known concentration were tested twenty times on one plate to assess. | ||||||

Three samples of known concentration were tested in twenty assays to assess. | ||||||
To assess the linearity of the assay, samples were spiked with high concentrations of mouse IL-4 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. | ||||||

This Mouse IL-4 ELISA Kit provides quantitative measurement of interleukin-4 in Mus musculus samples, supporting research into Th2-mediated immune responses, allergic inflammation, and alternative macrophage activation. Because IL-4 is often present at low picogram-level concentrations in vivo yet can rise sharply during Th2-polarized responses or allergic challenge, accurate quantification across this dynamic range is critical for meaningful experimental readouts.
Detection Range: The 6.25–400 pg/ml range spans the concentrations typically observed from baseline circulating IL-4 in naïve mice through the elevated levels found during helminth infection, OVA-induced airway inflammation, or Th2-skewed in vitro cultures, minimizing the need for extensive sample dilution in most disease models.
Sensitivity: At 1.56 pg/ml, the kit detects the characteristically low IL-4 levels present in unstimulated mouse serum or early-phase allergic responses, where this cytokine is notoriously difficult to capture due to rapid receptor-mediated consumption.
Sample Compatibility: Validation across serum, plasma, and tissue homogenates enables researchers to correlate systemic IL-4 levels with local tissue expression—for example, comparing circulating cytokine to lung homogenate concentrations in asthma models.
Assay Efficiency: The 50–100 µl sample volume and 1–5 hour protocol accommodate the limited serum volumes obtainable from individual mice, preserving samples for parallel cytokine measurements without requiring blood pooling.
This kit is well-suited for studies of allergic asthma, anti-helminth immunity, and M2 macrophage polarization.
