Figure 4. SIN-1 increases the interaction of PLB with PP2a.

Figure 4

A.) Representative western blot (IB) specific for PP2aC and PLBtotal following co-immunoprecipitation (Co-IP) with PLB in cardiac homogenates. Co-IP control #1: crosslinked control gel + homogenate; Co-IP control #2: homogenate (no antibody-coupled AminoLink Plus gel). NOTE: The results from two separate Co-IP experiments from different samples are shown for each experimental condition (CONT, SIN-1, etc.). B.) Pooled densitometry data (mean±S.E.M.) for PP2a band intensity normalized to PLBtotal with control (normal Tyrode), SIN-1 (200 μmol/L), and SIN-1+urate (500 μmol/L). Data displayed as arbitrary units (A.U.). *p<0.05 vs. Control; ‡p<0.05 vs. SIN-1; n = 5–6 hearts/group.
