Each lot has been tested for PPAR-gamma activation by using TransAM™ PPAR-gamma Kits. The signal intensity for PPAR-gamma activation in each lot is compared to the signal intensity obtained with extracts from unstimulated THP-1 cells (see figure). After the signals are blanked, the ratio of the signals from stimulated cells over unstimulated cells must be above 4. This ratio may vary depending on the basal level of PPAR-gamma activation in a given cell type.
