32P-end-labeled DNA fragment contains the AP-1–binding site sequence
The DNA was mixed with Fos, FosC (a fragment of Fos), or Jun (all of which would form a homodimer), or with a mixture of Fos and Jun or a mixture of FosC and Jun (both of which would form the two types of homodimer and the heterodimer). Reactions were analyzed by polyacrylamide gel electrophoresis, thenautoradiography. The results are shown in Figure 1.
This technique is called:
A. DNA footprinting.
B. electrophoretic mobility shift assay.
C. reporter gene assay.
D. immunoprecipitation.
