Generation of Riboflox/flox/PKP2flox/flox/Cre+ mice. (A) RiboTagflox/flox/-PKP2flox/flox mice were obtained crossing RiboTag mice (JAX B6N.129-Rpl22/J 011029) with PKP2cKO/αMyHC-Cre-ER(T2). Cre + and Cre- mice were tamoxifen-injected and used 21 days post injection (dpi). (B) Mice hearts were analyzed by western blot. The 23-kDa 3HA epitope-tagged ribosomal protein RPL22 was detected by an HA antibody. A heterozygous RiboTagflox/wt was used. For experiments, we used homozygous RiboTagflox/flox to increase 3HA-RPL22 expression and facilitate breeding scheme.
