Percentage of total CCL2 promoter DNA immunoprecipitated: -2578 A relative to -2578 G.

ChIP results from U87-MG cells transfected with -2578 A and G containing plasmids and activated with IL-1β for 3 hours. Results represent the proportional binding of each transcription factor to the -2578 A and -2578 G relative to the total DNA precipitated by each indicated antibody (A/A+G or G/A+G). Anti-IgG antibody was used as a negative control. The standard deviation is the same for both the -2578 A and -2578 G values since their sum is equal to 100. Therefore, the standard deviation is listed only once.
