Fig 7. In vivo beta-glucuronidase activity of tumors treated with E. coli (lux/βG).

Fig 7

(A) NOD/SCID mice bearing HCT116 tumors were i.v injected with 4 x 107 c.f.u. E. coli (lux) or E. coli (lux/βG). After 4 days, 500 μg FDGlcU was i.v. injected into the mice. After 30 min, the luminescence (representing bacterial numbers) and fluorescence (representing beta-glucuronidase activity) in tumors were detected on an IVIS Spectrum (n = 3). (B) The mean luminescence and fluorescence intensities in tumors are shown. Unit is photons sec-1cm-2sr-1. Bars, s.d. * P < 0.05.
