Na⁺ transport kinetic constants for NHE1 in <i>Amphiuma</i> RBCs stimulated to steady-state in isosmotic solution with 500 nM CLA, or mildly hyperosmotic (1.2×IR) solution ± CLA.

Kinetic constants are expressed as Km or Jmax ± SEM. Values for Km are similar in all 3 conditions, while Jmax is increased by CLA treatment relative to hyperosmotic medium alone. Estimated* (by hyperbolic curve-fit) Jmax activity in the unstimulated isosmotic condition is also shown.
