Fig. 3. Effect of Dextran 6000 on release of LDH from HeLa cells infected with Y.pseudotuberculosis. HeLa cells were infected with a YopEHJ^– mutant (YP27) or a YopE^– mutant (YP6) in the presence or absence of 30 mM Dextran 6000 or 30 mM sucrose. LDH release 3 h post infection was determined as described in the legend to Figure 2.
