Table 1. Na⁺ transport kinetic constants for NHE1 in Amphiuma RBCs maximally stimulated to steady-state in hyperosmotic (1.6×IR) media with or without 500 nM CLA treatment.

Treatment	Km(mM Na+)	Jmax (mmoles Na+/Kg dcs minute)
Hyperosmotic (1.6×IR)	52.1±3.9	23.9±0.8
Hyperosmotic (1.6×IR) + CLA	42.0±8.4	23.2±1.8

Kinetic constants are expressed as K_m or J_max ± SEM. Values for K_m and J_max are virtually identical in both treatment conditions.
