Fig. 4. Secreted fluid Texas Red concentration ([Texas Red]sf) as a
function of bathing saline Texas Red concentration for cricket tubules set up
in Ramsay assays. Each point shows the mean ±
S.E.M. for N=613 tubules. The
solid line represents the fit to the MichaelisMenten equation by
non-linear regression analysis. As discussed in the text, the point at 50
µmol l1 Texas Red was excluded from the curve-fitting
procedure. The inset shows the ratio of the concentration of Texas Red in the
secreted fluid to that in the bathing medium (S/M) as a function of bathing
medium Texas Red concentration.
