Abstract
This invention is concerned with two closely related assay methods for detecting the presence of Neisseria bacteria in a fluid sample. Both of the methods utilize radiolabelled antibodies specific to the enzyme released upon lysis of the bacteria. In the first method, denominated immunoradiometric assay (IRMA), the enzyme is reacted with soluble purified radioactive antibodies. In the second method, known variously as 'two-site IRMA', 'junction test', or 'sandwich technique', contemplates initial insolubilization of the enzyme and thereafter the reaction with soluble purified radioactive antibodies. The structure and composition of the enzyme released upon lysis of Neisseria bacteria are not fully comprehended but it has the capability of oxidizing 1,2-propanediol and reducing nicotinamide-adenine-dinucleotide (NAD). This has led to the name 1,2-propanediol dehydrogenase being proposed for the enzyme.
