Intra-assay Precision (Precision within an assay): CV%<8% | ||||||
Three samples of known concentration were tested twenty times on one plate to assess. | ||||||
Inter-assay Precision (Precision between assays): CV%<10% | ||||||
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 human IL-6 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. | ||||||

This ELISA kit provides quantitative measurement of interleukin-6 (IL-6) in human samples, supporting research into this pleiotropic cytokine's central role in inflammatory signaling, acute-phase responses, and immune dysregulation. Because IL-6 levels can span orders of magnitude between healthy baseline and active disease states such as sepsis or cytokine storm, the kit is designed to capture both constitutive and induced expression across diverse biological compartments.
Detection Range: The 4.7–300 pg/mL range covers basal circulating IL-6 in healthy serum (typically 1–5 pg/mL with dilution consideration) through the elevated concentrations seen in chronic inflammation, autoimmune flares, and post-surgical responses, minimizing the need for extensive sample dilution in most clinical and in vitro stimulation experiments.
Sensitivity: At 2.35 pg/mL, the kit detects the low-picogram concentrations characteristic of unstimulated peripheral blood, early infection, or conditioned media from resting monocytes and fibroblasts where IL-6 secretion is minimal.
Sample Compatibility: Validation across serum, plasma, cell culture supernatants, tissue homogenates, saliva, and urine enables researchers to correlate systemic IL-6 levels with local tissue production or mucosal secretion within a single study, supporting translational and compartment-specific analyses.
Assay Efficiency: A 50–100 µL sample requirement and 1–5 hour protocol accommodate limited-volume specimens from pediatric cohorts or primary cell cultures while supporting same-day data acquisition in high-throughput screening.
This kit is particularly suited for studies in sepsis biomarker profiling, rheumatoid arthritis monitoring, and CAR-T-associated cytokine release syndrome research.
