Human Interferon alpha-14 (IFNA14) ELISA Kit

A sandwich ELISA kit from Assay Genie enables quantitative measurement of human interferon alpha-14 (IFNA14) in research samples. The assay uses a colorimetric detection method and is reactive with human specimens, supporting studies of antiviral immunity, autoimmune disorders, and inflammatory conditions.

Validated for serum, plasma, tissue homogenates, cell culture supernates, and other biological fluids, the kit delivers a detection range of 15.6–1000 ng/mL with a sensitivity of 9.8 ng/mL. Precision is reported as an intra-assay CV of 4.5% and an inter-assay CV of 8.9%. Linearity has been demonstrated in serum, EDTA plasma, and heparin plasma across dilutions from 1:2 to 1:16. Recovery averages 98% (range 92–104%) for serum and 100% (range 94–106%) for plasma.

The assay specifically detects natural and recombinant human interferon alpha-14, a secreted cytokine produced by macrophages with antiviral activity. The kit is shipped at +4°C, stored at -20°C, and is intended for research use only.
