However , despite its ability to activate transcription of a transfected reporter gene , the factor is apparently unable to bind to the endogenous Ig heavy chain enhancer in non- lymphoid cells : In previous experiments by others , the characteristic in vivo footprint of this factor , designated NF-muE3 , was detected in B cells but not in non-B cells .
