This study evaluates commercially available glucagon receptor antibodies and identifies a specific antibody for GCGR localization, confirming liver and kidney as primary glucagon targets.

This study shows that RYGB surgery increases postprandial secretin levels, identifies glucose-sensitive S-cells in the distal small intestine, and demonstrates secretin's effects on glucose regulation.

The paper identifies alanine, arginine, and proline as amino acids that stimulate glucagon secretion in mice, showing their metabolism depends on glucagon receptor signaling.
