Figure 6: Validation of expression profile of vinculin (VCL) in HF subjects. PBMC protein lysates (5 µg) from NH controls () and HF subjects () were subjected to sandwich and biotin-switch ELISA, respectively, for the detection of VCL (a) and SNO-modified VCL (b) levels. Mann Whitney test was performed to evaluate the significance (, ).
