To monitor tumor burden in vivo, blood samples were obtained weekly from the saphenous vein starting 1 week after ID8-p53−/−GLuc injection into C57BL/6 mice and until 5 weeks after tumor cell injection. Blood was centrifuged at 2,000 rpm for 15–20 min at room temperature, and plasma was recovered and stored at −80°C. Once thawed, 3 μl of every sample was diluted in PBS containing 0.1% BSA. Gaussia luciferase level in each sample was quantified by exposure to Coelenterazine-SOL (Nanolight) using a BioTek Synergy Mx plate reader and Gen5 2.07 Software.
