Pages F601-F614: S. L. Alper, A. K. Stuart-Tilley, D. Biemesderfer, B. E. Shmukler, and D. Brown. "Immunolocalization of AE2 anion exchanger in rat kidney." Some panels of Figs. 5 and 11 were misidentified. In the RESULTS, on p. F606 and F607 (in AE2 in cell surface membranes of inner medulla), the single reference to Fig. 5a in the second sentence should refer to Fig. 5b, and the two references to Fig. 5b should refer to Fig. 5a. The corrected text should read as follows:

AE2 in cell surface membranes of inner medulla. Figure 5 shows double immunostaining of an SDS-pretreated transverse section through the upper one-third of the inner medulla. In Fig. 5b, monoclonal anti-AE1 again detected AE1 in the basolateral membranes of type A IC (arrows) and in retained red blood cells. In Fig. 5a, anti-AE2 aa 1224-1237 detected weaker basolateral staining in the IMCD cells, in addition to AE1 staining in the same type A IC (arrows) and red blood cells. The narrow diameter AE2-positive profiles in Fig. 5a likely represent thin limbs.

Also, on p. F611, in the legend to Fig. 11, the reference to panels G-L in the first sentence should refer to panels J-L. Therefore, the first sentence of this legend should read as follows:

Specificity of immunostaining in rat kidney cortex with anti-AE1 aa 917-929 (A-C) and with anti-AE2 aa 1224-1237 (D-L) with (D-I) or without SDS pretreatment (J-L).
