Product specifications

Intended use

This ELISA Pro kit is intended for the quantification of human IFN-α in serum, plasma, and cell culture supernatants. For research use only. Not for use in diagnostic procedures.

Serum/Plasma samples

The ELISA diluent included in this kit blocks heterophilic antibodies from cross-linking the assay antibodies, thereby preventing false-positive read-outs. Heterophilic antibodies are commonly found in human serum/plasma and can also be present in other species. The ELISA diluent has been validated using from healthy human blood donors.

ReactivityHuman, Non-human primates
SpecificityThis kit is based on a matched pair of mAbs enabling specific detection of human IFN-α. Subtypes 1/13, 2, 4, 5, 6, 7, 8, 10, 14, 16, and 17 are detected.
Cross-reactivityThe mAbs cross-react with IFN-α from non-human primates (NHP). For more information please check the Cross-reactivity guide section below.

Shipping and Storage

ShippingShipped at ambient temperature.
StorageStore detection mAb, Streptavidin-HRP, buffers/solutions, and substrate at 4-8 °C upon receipt. The ELISA standard should be stored at -20 °C. Plates may be kept at room temperature.
Shelf lifeAt least 12 months from date of receipt.
Standard range5-4000 pg/ml
Sensitivity2 pg/ml

The lowest concentration that can be detected, but not necessarily quantified with precision and accuracy. This was determined by adding 10 standard deviations to the mean OD of background wells.
Mean standard curve from repeated runs of human Interferon-alpha (IFN-α) ELISA Pro kit.

The systems reactive with NHPs are either based on cross-reactive human kits or specifically developed monkey kits (NHP).

Cross-reactivity verification tests have been performed in ELISpot and/or ELISA by Mabtech and/or by others. Evaluations of assays with less solid evidence of cross-reactivity are shown as symbols within parentheses.

Analyte description

Interferon-α and interferon-β are type I interferons. These antiviral cytokines are mainly produced by virus-infected cells after sensing the presence of danger signals such as viral DNA or RNA. IFN-α and IFN-β act through the same receptor and initiate an anti-viral response, affect immune regulation, T cell responses, and also anti-tumor effects have been shown. A key producer of type I interferons is the plasmacytoid dendritic cell. Additionally, IFN-α is secreted by lymphocytes, macrophages, fibroblasts, and dendritic cells. 

In humans, interferon-α has 13 subtypes: IFN-α 1, 2, 4, 5, 6, 7, 8, 10, 13, 14, 16, 17, and 21.

In mice, there are 14 IFN-α subtypes: 1, 2, 4, 5, 6T, 7/10, 8/6, 9, 11, 12, 13, 14, 15 (A), and B. There are also different allelic forms of mouse IFN-α subtypes 1, 7/10, 8/6, and 11 in mouse strains 129/Sv and C57BL/6.
