A PCDH7 antibody detects a single band of ˜110 kDa in luciferase RNAi (luc), PCDH1 RNAi HeLa cell lysates, but this band is not detectable in PCDH7 and PCDH1 and PCDH7 RNAi cells. α‐tubulin was used as a loading control (left). HeLa Kyoto cells stably expressing PCDH7‐LAP‐tagged BAC transgenes treated with luciferase RNAi (control) and 150 nM (1×) and 300 nM (2×) PCDH1 esiRNA and blotted against anti‐GFP, anti‐PCDH1, and anti‐actin antibodies. PCDH1 bands were reduced in PCDH1 RNAi cells, whereas mouse GFP::PCDH1 was not affected by the esiRNA treatment (right).
