Figure Lengend Snippet: Protein expression of Ca2+ handling proteins. A: example Western blots of sarco/endoplasmic reticulum Ca2+ ATPase (SERCA; 100 kDa), phospholamban (PLB; 6 kDa), the Ser16 phosphorylation site of PLB (SER16-PLB; 6 kDa), the Thr17 phosphorylation site of PLB (THR17-PLB; 6 kDa), the Na+-K+-ATPase (NA/K; 100 kDa), sodium-calcium exchanger (NCX; 120 kDa), ryanodine receptor (RYR; 565 kDa), and calsequestrin (CSQ; 50 kDa). Summary data of protein expression (relative to CSQ) of SERCA (B), PLB (C), SERCA/PLB ratio (D), SER16-PLB (E), THR17-PLB (F), Na+-K+ ATPase (G), NCX (H), and RYR (I). Data shown are from whole heart homogenates of CON, AB, and AB-LIT groups; n = 5–7 animals per group. *P < 0.05 vs. CON. #P < 0.05 vs. AB. §P < 0.10 vs. CON and AB.
Article Snippet: Blots were incubated overnight (25°C) with the primary antibody against SERCA2a (1:1,000; ThermoFisher Scientific), phospholamban (PLB; 1:1,000; ThermoFisher Scientific), sodium-calcium exchanger (NCX; 1:1,000; ThermoFisher Scientific), Na + -K + -ATPase (1:1,000; ThermoFisher Scientific), ryanodine receptor (RyR; 1:1,000; ThermoFisher Scientific), Ser16 phosphorylated PLB (1:1,000; Badrilla), Thr17 phosphorylated PLB (1:1,000; Badrilla), and calsequestrin (CSQ; 1:10,000; ThermoFisher Scientific).
