IHC of MYL3, MYL4, MYOM1, and PAM in the left ventricle and left atrium. A) Ventricular staining of MYL3 showing homogeneous staining. B) Atrial staining of MYL3 showing mosaic staining with ~85% of cells being positive. C) Ventricular staining of MYL4 showing ~15% staining. D) MYL4 staining of the subendocardium of the ventricle showing a marked increase in positive cells just along this edge. E) Atrial staining of MYL4 showing homogeneous staining across all myocytes. F) MYOM1 staining of the ventricle. G) MYOM1 staining of the atrium showing heterogenous staining intensity. H) PAM staining of the ventricle showing rare (~5%) positive cells. I) PAM staining of the atrium showing a granular staining pattern in most cells. Bar = 300 μm.
