Glycoprotein-like large glucagon immunoreactive species in extracts of the fetal bovine pancreas.
Large glucagon immunoreactive substances, extracted from the fetal bovine pancreas and separated by gel filtration in the presence of 6 M guanidinium-hydrochloride, were submitted to lectin-sepharose affinity column chromatograph. Gel-filtered peak I (approximately 45 K delta) and peak II (approximately 10 K delta) interacted biospecifically with concanavalin-A- and wheat-germ-lectin-sepharoses, suggesting glycoproteins as possible constituents of large glucagon immunoreactive substances in extracts of the fetal bovine pancreas. The glucagon-like immunochemical identity of the lectin-sepharose-bound substances was further substantiated by binding to antiglucagon antibodies-sepharose and by characteristic proportional dilutions in the glucagon radioimmunoassay.[1]References
