FIG. 6.
Sensitivity of Lig expression and release to sodium chloride concentrations. L. interrogans Fiocruz L1-130 grown in EMJH was collected by centrifugation and resuspended in EMJH (lanes 1 and 2) or EMJH containing an additional 40 mM NaCl (lanes 3 and 4), 80 mM NaCl (lanes 5 and 6), or 120 mM NaCl (lanes 7 and 8). The cultures were incubated for 24 h and examined for Lig expression and release following separation of proteins on an SDS-PAGE gel (10% polyacrylamide) gel. c, cells; s, culture supernatant fluid.
