Gel-shift analysis reveals the constitutive presence of nuclear factors in resting PBL that bind to the proximal AP-1 site of the IL-2 promoter and that contain immunoreactive c-Jun but not c-Fos protein.
 ( cell type: resting PBL, None) , ( protein: c-Jun, None) , ( cell type: PBL, None) , ( DNA: IL-2 promoter, None) , ( DNA: proximal AP-1 site, None) , ( protein: c-Fos, None)
