Product Description
The BioDeviceLab Human Interleukin-10 (IL-10) ELISA Kit is a high-performance enzyme-linked immunosorbent assay developed for the quantitative determination of IL-10 in biological samples. IL-10 is a key anti-inflammatory cytokine produced by immune cells and epithelial cells that plays a central role in limiting excessive inflammatory responses and maintaining intestinal immune homeostasis.
IL-10 suppresses the production of pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-6, promotes epithelial barrier recovery, and regulates immune tolerance to commensal microbiota. Dysregulation of IL-10 signaling is strongly associated with inflammatory bowel disease, chronic intestinal inflammation, and impaired mucosal healing. In gut-on-chip platforms, IL-10 serves as a critical biomarker for evaluating immune resolution, epithelial recovery, and therapeutic efficacy of anti-inflammatory or immunomodulatory interventions. This assay combines high analytical sensitivity, strong specificity, and robust reproducibility, making it suitable for both mechanistic immune regulation studies and advanced biodevice validation workflows.
Intended Use
This kit is intended for the quantitative determination of human IL-10 in:
• Serum
• Plasma
• Cell culture supernatants
• Tissue culture media
Applications include gut-on-chip immune regulation studies, host–microbiome tolerance modeling, inflammatory bowel disease research, epithelial recovery assessment, and biodevice calibration and benchmarking.
Assay Principle
This assay employs a sandwich ELISA format:
• IL-10 present in the sample binds to capture antibodies immobilized on a 96-well microplate.
• A biotinylated detection antibody specific to IL-10 binds to the captured protein.
• An enzyme conjugate is added, followed by chromogenic substrate (TMB).
• The enzymatic reaction generates a colorimetric signal measured at 450 nm.
• Absorbance is directly proportional to the IL-10 concentration in the sample.
Calibration Curve
• A calibration curve is generated using recombinant human IL-10 standards with known concentrations.
• Mean absorbance values are plotted against IL-10 concentration on a semi-logarithmic scale.
• A four-parameter logistic (4PL) regression model is recommended for curve fitting.
• Sample concentrations are calculated by interpolation from the standard curve.
Analytical Performance
