Figure 5: Immunohistochemistry Sections Labeling the GLP-1R With and Without mAb 3F52 Antibody

(A) Pancreatic tissue, high-power (60×), positive control with monoclonal 3F52 antibody, showing moderate widespread staining for glucagon-like peptide 1 receptor (GLP-1R) with high staining in beta cells. (B) Pancreatic tissue, negative control without mAb 3F52 antibody, high power (60×), confirming no staining. Right ventricular sections from an explanted heart with ischemic heart disease, (C) low power and (D) high power (60×), confirming staining with mAb 3F52 for GLP-1R in right ventricular tissue. Matched left ventricular sections, (E) low power and (F) high power (60×), confirming staining with mAb 3F52 for GLP-1R in the left ventricle. Scale is 100 μm in all images.
