Anti-IFN-ω Antibody

Raised in rabbits against human interferon omega, this unconjugated polyclonal reagent from Antibodies.com supports Western blot and ELISA workflows that probe type I interferon signaling. IFN-ω is a leukocyte-expressed cytokine with established antiviral and antiproliferative activity, sharing receptor usage with IFN-α and IFN-β and frequently examined in viral restriction studies, lupus transcriptome work, and comparative innate immunity screens across mammalian species. Each vial contains 100 µl of antibody suitable for multiple blots. For storage, aliquot upon arrival and freeze at -20 °C to preserve titre across repeated freeze-thaw cycles, keeping the solution protected from light. The reagent is reactive with human samples and has been used to track IFN-ω induction in stimulated peripheral blood mononuclear cells and virus-infected primary cultures. Researchers comparing feline, equine, or bovine orthologs should validate cross-reactivity empirically, since IFN-ω sequence divergence between species is substantial. Provided in research-use-only format, this antibody enables reproducible detection of a less-abundant but biologically informative branch of the type I interferon family.
