Immunoprecipitation of big WT1 isoforms with C-19 antibody but not with command non-immune IgG was verified. Even so,PLOS Just one | DOI:ten.1371/journal.pone.0130578 June 19,ten /Novel WT1 Spliced IsoformEx4a(+)WT1 isoform wasn't co-precipitated with main WT1 isoform using C-19 antibody (Determine B in S2 Fig). Therefore, it appeared that Ex4a(+)WT1 isoform did not bodily associate with key WT1 i
