Interferons (IFNs) are central cytokines that orchestrate the body’s innate immune and antiviral responses. These signaling proteins trigger an antiviral state in neighboring cells, inhibit pathogen replication, and regulate inflammation—making fundamental interferon function a critical focus in viral pathology, autoimmunity, and immuno-oncology.
To support targeted research, interferons are classified into three distinct structural types, each utilizing specific receptor complexes and the core JAK-STAT signaling pathway:
Because these cytokines are transiently expressed and act at low concentrations, precise quantification is essential. Reddot Biotech’s high-sensitivity IFN ELISA kits are engineered to detect these specific targets across sample types. Whether measuring IFN alpha in early immune activation or tracking IFN-γ in the tumor microenvironment, our validated kits empower scientists to explore complex disease mechanisms with consistent, reproducible data.
Interferons (IFNs) are a critical family of signaling cytokines that orchestrate the body’s primary response to pathogens and malignant transformations. By binding to specific cell surface receptors, IFNs activate the JAK-STAT signaling pathway, leading to the transcription of hundreds of interferon-stimulated genes (ISGs). Research involving IFN quantification typically focuses on two primary domains:
Type I interferons (such as IFN-α and IFN-β) and Type III interferons (IFN-λ) are the frontline defenders against viral infections. Upon detecting viral nucleic acids, infected cells rapidly secrete these cytokines to establish an "antiviral state" in neighboring, uninfected cells. This signaling cascade halts viral replication, promotes the degradation of viral RNA, and initiates the recruitment of adaptive immune cells. Measuring these specific subtypes is essential for studies targeting infectious diseases, vaccine efficacy, and autoimmune responses.
In cancer research, Type II interferon (IFN-γ) plays a dual role in tumor immunology and surveillance.
Accurately quantifying these cytokines requires highly sensitive and validated assays. Explore our selection of target-specific IFN ELISA kits below to find the exact specifications required for your sample matrix and research focus.
Q: How do interferons create an "antiviral state" in cells?
A: When a cell detects viral nucleic acids, it rapidly secretes interferons. These cytokines bind to receptors on neighboring, uninfected cells, activating the core JAK-STAT signaling pathway. This cascade leads to the transcription of hundreds of interferon-stimulated genes (ISGs), which produce proteins that halt viral replication, degrade viral RNA, and recruit adaptive immune cells.
Q: Are these kits sensitive enough to detect naturally low levels of IFNs?
A: Yes. Because interferons are often transiently expressed and act at very low concentrations in the body, our IFN ELISA kits are specifically engineered for high sensitivity and specificity. They are optimized to accurately detect low-abundance analytes and provide consistent, reproducible data.
Q: Do you offer kits for non-human animal models?
A: Yes, we support diverse in vivo and in vitro research models. We offer over 100 different kits with a wide variety of reactivities, including Human, Mouse, Bovine, Canine, Rabbit, and other hard-to-find species.
Q: How are Traditional and Ready-to-Use ELISA kits different?
A: Ready-to-Use ELISA kits have some slight optimizations to make them more user-friendly, but our Traditional kits have a lower price point. Both options have the same high level of quality and sensitivity.
Q: How should I store my Traditional ELISA kits?
A: Always store kits as directed in the manual or on labels. For Traditional ELISA kits from Reddot Biotech, store the TMB Substrate, Wash Solution Concentrate, and Stop Solution at 4oC, and the rest of the components at -20oC for up to 12 months.
Q: What dilution should I use for my samples with Traditional ELISA kits?
A: The dilution for your samples will depend on the concentration of the analyte in your sample. For best results, we recommend performing a preliminary concentration gradient experiment to determine the optimal dilution ratio for your samples before you begin.
