摘要: A novel peptide of the formulaH--Ser--Arg--Arg--Ala--Gln--Asp--Phe--Val--Gln--Trp--Leu--Met--Asn--Thr--OHis the 16-29 fragment of glucagon and can be conjugated with a protein such as albumin or modified albumin using glutaraldehyde or 3-(2'-benzothiazolyl-dithio) propionate succinimide ester as a conjugation reagent. The conjugated peptide can be used to sensitize a mammal by administering the conjugated peptide subcutaneously, after which the blood is collected from the mammal and antibodies concentrated from the blood, which antibodies are then useful in assay methods for trace amounts of glucagon in human blood.
