this was shown using the electrophoretic mobility shift assay on a dna fragment of human gamma-globin gene promoter ( -156 to -201 ) , on the same fragment with a point mutation ( t to c mutation ) known to have an increased affinity of binding for nfe 1 , on a dna fragment of human histone h2b promoter and on a dna fragment of mouse alpha 1 globin promoter .
