Here, we describe the effect of 383-bp (delta383) and 99-bp (delta99) sequences containing the PYBF -binding site on transcription from various globin and non-globin promoters, using a transient assay with the cat reporter gene in murine erythroleukemia (MEL) cells , a cell line with abundant PYBF activity .
 ( cell line: murine erythroleukemia (MEL) cells, None) , ( protein: PYBF, None) , ( DNA: PYBF -binding site, None) , ( protein: PYBF, None) , ( DNA: cat reporter gene, None)
