    摘要: Apparatus for performing an immunoassay, comprises in combination a reaction tube closed at its bottom, and in the reaction tube a molded element having on its surface material having specific binding ability for a component in a liquid specimen to be assayed. The shape of the surface of the element adjacent the interior surface of the tube is the complement of the shape of the interior surface of the tube. A spacer rib is provided on the element, in contact with the interior surface of the tube. This rib holds the element in such position in the tube that the surfaces of complementary shape of the element and tube are shaped from each other a small but constant distance. A thin layer of constant thickness of a liquid specimen for immunoassay is thus receivable between the complementary surfaces. This arrangement increases the contact surface of the liquid medium in the reaction tube by the element, by establishing a homogeneous uniform layer of liquid medium. This avoids the need for stirring and shaking and reduces the required volume of the specimen to be assayed.

    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.
