Evidence for the presence of glucagon-like immunoreactivity (GLI) in the pancreas.
Glucagon-like immunoreactivity (GLI), which can be separated from glucagon by isoelectric focusing, has been detected in partially purified canine pancreatic extracts. Like gastrointestinal GLI, this insular GLI reacts with crossreacting antiserum 78J but not with glucagon "specific" antiserum 30K and has an isoelectric point (pl) of 9.5, whereas canine pancreatic glucagon has a pl of 6.25. When combined with glucagon, the GLI-glucagon mixture gives 48J assay values between GLI and this crossreacting antiglucagon serum and thus conceals it in glucagon-containing extracts.
