Figure 3From: Mitochondrial activities in human cultured skin fibroblasts contaminated by Mycoplasma hyorhinisPhosphate acetyltransferase activity in titrated suspensions of Mycoplasma hyorhinis. Measurement of DTNB reduction as a function of organisms/ml. Notice that 9 × 106 organisms represents about 30 μg protein, one color-changing units (CCU) corresponding roughly to 10 to 100 organisms [29].Back to article page
