Immunoprecipitation of big WT1 isoforms with C-19 antibody although not with command non-immune IgG was verified. Even so,PLOS A person | DOI:10.1371/journal.pone.0130578 June 19,ten /Novel WT1 Spliced IsoformEx4a(+)WT1 isoform wasn't co-precipitated with key WT1 isoform utilizing C-19 antibody (Determine B in S2 Fig). Consequently, it appeared that Ex4a(+)WT1 isoform did not bodily associate with
