Horseradish peroxidase conjugated goat anti rabbit lgg

Both H9C2 cells and myocardial tissues were harvested for Western blot analysis (Western Blot Detection Kit, Elabscience) following standard protocol according to the manufacturer’s instructions and Towbin system buffer was used. Primary antibodies used in Western blot were as follows: anti-GLP-1R (1:200, Abcam, UK), anti-Akt (1:200, Abcam, UK), anti-p-Akt (1:200, Abcam, UK), anti-PI3K (1:500, Santa Cruz, USA), anti-PKC (1:500, Abcam, UK), anti-PKCα (1:500, Abcam, UK), anti-PKCβ (1:500, Abcam, UK), anti-PKCγ (1:500, Abcam, UK), anti-PKCδ (1:500, Abcam, UK) and anti-β-actin (1:500, Santa Cruz, USA). Secondary antibodies were horseradish peroxidase-conjugated goat anti-rabbit lgG (Santa Cruz, USA) at 1:5000 dilution. The results were visualized using an enhanced chemiluminescence system (ECL, Amersham). Densitometric analysis was conducted using ImageJ software (NIH, USA).
