IFN-alpha 2 (clone N39), anti-human

Source:
A BALB/c mouse was immunized with E. coli derived recombinant human IFNα2c.
Fusion partner: NS-1.

Specifications:
The alpha interferons are involved in virus resistance in target cells for these viruses. They are known to block cell proliferation and to regulate MHC class I antigen expression. The IFNαfamily has over 20 genes and pseudogenes in two families (I and II), one with a mature length of 166aa and one of 172aa. Cells producing IFNαare lymphocytes, monocytes, macrophages and cell lines such as Namalwa and KGI. Bioassays for IFNαinclude cytopathic effect blocking, by viruses such as VSV, SFV and BMCV, on their target cells. A number of receptors for IFNαare now known and seem to be expressed on most cell types. N39 is specific for human IFNα2 and does not cross react with human IFNα1. N39is directed against immunodominant epitope site I (aa112-148).

Species reactivity:
Positive: human.

Applications:
N39 can be used for the detection of human IFNα2 in ELISA and Western blot. It can be paired with IFNα2 mAb N27, to form an EIA to measure IFNα2.
