Immunofluorescence localization of cMyBP-C in cat myocardium. Top: Immunofluorescence staining using the C-pro antibody showed the expected doublet pattern of cMyBP-C localization (green) in myocardium from wild-type (A), A31P heterozygous (B), and A31P homozygous (C) cats. Staining for α-actinin (red) was used to label sarcomere Z-lines as a reference. Bottom: Immunofluorescence localization using the A31P antibody showed that mutant A31P cMyBP-C is also properly incorporated into sarcomeres as demonstrated by the characteristic doublet pattern of cMyBP-C localization (green) in myocardium from heterozygous (E) and homozygous (F) cats but not wild-type (D) cats that lack A31P cMyBP-C. α-actinin localization (red) was used to label sarcomere Z-lines as a reference.
