2.7.4. Insulin, Glucagon, GIP, and GLP-1
Commercially available ELISA kits were used to determine the concentrations of insulin (#10-1113-01, MERCODIA), glucagon (#10-1271-01, MERCODIA), GIP (#10-1258-01, MERCODIA) and GLP-1 (#10-1278-01, MERCODIA). The concentration of glucagon was below the lower limit of detection in 11 samples. These values were dispersed across all groups. Seven values were below the lower limit of detection for GIP; again, values were dispersed across all groups.
