In vivo Gluc expression and secretion. Gluc activities were determined in liver homogenates and EDTA-blood of C57 mice 24 hr after HTV injection with either pCMV-Gluc or phAAT-Gluc plasmids. Luciferase activities were normalized by subtracting background signals derived from samples collected from mock-injected animals, and expressed as ΔRLU per µg protein or per µl of blood. The bars represent the mean values.
