Specificity: Specific for human FUS protein. Other species not tested. Reactivity with mouse (but not X. laevis) FUS is likely owing to identity of sequence between mouse and human FUS at the site to which the epitope maps.
Immunogen: A synthetic peptide which maps to a region between residues 400 and 450 of human fusion (involved in t (12;16) in malignant liposarcoma) using the numbering given in SwissProt entry P35637 (GeneID 2521).
