: This 36-bp probe forms two distinct cell-specific protein-DNA complexes, labeled C1 and C2 .
: These complexes are observed when the sequence is incubated with nuclear extracts from specific cell lines, such as H4IIEC3 cells . 22924.rar
: The binding is sensitive to the surrounding genetic architecture. Deleting specific flanking sequences (9-bp from the 5' end and 7-bp from the 3' end) reduces the formation to only a single complex. Scientific Context: PPAR and RXR : This 36-bp probe forms two distinct cell-specific
