Figure 7. Ca2+-activated K+ channel expression in colon tissue from WT and Kcnn4 null (KO) mice.

Figure 7

Agarose gel electrophoresis of RT-PCR products is shown for the indicated transcripts. Predicted product sizes were KCNN1 (241 bp), KCNN3 (275 bp), KCNN4 (957 bp), KCNMA1 (392 and 218 bp), KCNMB1 (246 bp) and KCNMB4 (285 bp). RT–, negative control omitting reverse transcriptase. C+ is a positive control from parotid gland cDNA, except for KCNN1 and KCNN3 which were done on brain cDNA. Arrows point to different number of base pairs as indicated on 100 or 1000 bp ladders.
