Figure 6. Processing of DSP-PP240 in conditioned medium is Zn-dependent.

Figure 6

(A) Stains-All staining of DSP-PP240 cleavage. Lane 1: CM0–3d of virus-infected cells without further incubation. Lane 2: CM0–3d from virus-infected cells incubated for an additional 3days. Lane 3: Same reaction as lane 2 except with addition of EGTA (22 mM). Lane 4: Same reaction as lane 2 except with addition of 1mM 1,10-phenanthroline. Lane 5: Same reaction as lane 2 except with addition of 1 mM 1,10-phenanthroline and 1 mM ZnCl2. M represents size marker. (B) Quantification of DSP-PP240 processing shown in panel A and two similar gels. Numbers 1–5 correspond to lanes 1–5. Error bars represent standard deviation of the mean.
