Effect of pH on the 15-min uptake of 10 µM [3H] carnosine in SKPT cell monolayers at 37°C from the apical (A) compartment (basolateral pH maintained at 7.4) and from the basolateral (B) compartment (apical pH maintained at 6.0). Data are expressed as mean ± SE (n=3–6). ** p < 0.01, as compared to pH 7.4. Relationship between pH and fractional ionization of carnosine (C).
