Atrial expression of Ca2+ handling proteins in different rodent species, pig, and human. (A) Immunoblots comparing the expression of ryanodine receptor 2 (RyR2), sodium-calcium exchanger 1 (NCX), SR Ca2+-ATPase 2 (SERCA2), sodium-potassium ATPase α1 subunit (Na,K), glyceraldehyde 3-phosphate dehydrogenase (GAPDH), phospholamban (PLN), and phospholemman (PLM). Insets document the intensity-corrected rabbit NCX and SERCA2 as used for quantification (arrowheads) and additional rabbit-specific antibody cross-reactions (asterisks). Also, the PLN pentameric (p) and monomeric (m) bands are indicated. See Supplementary Figure S4 for full blots and Supplementary Table S1 for clinical patient information. Immunoblot/GAPDH signals (B) and relative protein ratios (C) each normalized to human. M, mouse; Rt, rat; Rb, rabbit; P, pig; H, human. Student’s t-test P < 0.05, ∗∗P < 0.01.
