Question (56637) | Anti-Interferon beta antibody (Biotin) (ab84258)

Go to datasheet (ab84258)


Anti-Interferon beta antibody (Biotin) (ab84258). I noticed the website says it reacts with human IFN. Is there any reason why it shouldn't work to detect other species of IFN as well? I want to do immunofluorescence microscopy for mouse IFN in hepatocytes in culture. Second question: The website IF photo description mentions a secondary antibody. Is it possible to use a fluorophore-conjugated streptavidin instead?


Thank you very much for your interest in ab84258.
