the retention of m2,2,7 g-containing rna species by these antibodies is not due to association of snrnas or snrnps with heterogeneous nuclear rna ( hnrna ) or hnrnp ( and antibody recognition of 7-monomethylguanosine residues in hnrna ) , since the reaction still occurs after removal of hnrna or hnrnp by sucrose gradient centrifugation .
