This ELISA kit provides quantitative measurement of interleukin-17F (IL17F) in human samples, supporting research into Th17-mediated immune responses and mucosal inflammation. Because IL17F is often co-expressed with IL-17A yet exerts distinct signaling effects through IL-17RA/RC receptor complexes, precise independent quantification is essential for dissecting their individual contributions to inflammatory pathology.
Detection Range: The 3.9–250 pg/mL range aligns with circulating IL17F concentrations reported in healthy individuals and elevated levels observed in psoriasis, inflammatory bowel disease, and asthmatic airways. Most serum and plasma samples can be measured directly without dilution, though highly inflamed tissue homogenates may require pre-dilution.
Sensitivity: At 1.95 pg/mL, the kit detects IL17F in low-abundance conditions such as unstimulated PBMC supernatants or serum from healthy donors, where concentrations frequently fall below 10 pg/mL.
Sample Compatibility: Validation across serum, plasma, cell culture supernatants, and tissue homogenates enables researchers to correlate systemic IL17F levels with local tissue production and in vitro Th17 polarization outputs within a single study.
Assay Efficiency: The 1–5 hour protocol and 50–100 µL sample volume accommodate limited-volume specimens from mucosal biopsies and primary Th17 differentiation cultures requiring longitudinal sampling.
This kit is particularly suited for studies in psoriasis pathogenesis, airway inflammation, and Th17 subset functional characterization.
