this antigen was distinguished from the previously reported nuclear chromatin antigen nag-1 ( 19 ) by the findings that tumor nucleolar antibodies which formed immunoprecipitin bands with no-ag1 did not do so with nag-1 and that tumor cytosol , which contains nag-1 , formed immunoprecipitin bands with tumor chromatin antibodies but not with antibodies to tumor nucleoli .
