Human Interferon Alpha 4 (IFNa4) ELISA Kit

A quantitative immunoassay from Assay Genie, this ELISA kit enables sensitive measurement of human interferon alpha 4 (IFN-α4), a type I cytokine central to antiviral innate immunity. IFN-α4 is encoded within the IFN-alpha gene cluster on chromosome 9p21 and signals through the IFNAR1/IFNAR2 receptor complex, driving transcription of interferon-stimulated genes and establishing an antiviral state in neighboring cells. The kit supports immunology, virology, and inflammation research, where IFN-α4 expression is investigated as a biomarker of pathogen recognition and interferon pathway activation.

Researchers apply the assay to human-derived samples relevant to viral infection studies, autoimmune disease models, and vaccine response characterization. It is compatible with in vitro cell culture supernatant analysis as well as tissue-derived and cell lysate preparations. Standard curve-based quantification follows the included protocol, and the kit ships with all buffers, plates, and detection reagents required to complete the workflow. Reagents are supplied in vials for research use only and should be handled per the enclosed instructions to preserve antibody binding activity across runs.
