This identification, initially made by microsequence analysis , was verified by showing that (i) LR1 -DNA binding activity increased in B cells transfected with a nucleolin cDNA expression construct ; (ii) LR1 -DNA binding activity was recognized by antibodies raised against recombinant human nucleolin ; and (iii) in B cells transfected with epitope-tagged nucleolin expression constructs , the LR1 -DNA complex was recognized by the anti-tag antibody .
