Complexed with αι-Proteinase Inhibitor

Summary: A solid phase, enzyme-linkcd immunoassay is described for the quantitative determination of the complex of human granulocyte elastase (EC 3.4.21.37) with αι-proteinase inhibitor. The assay employs anti-body-coated test tubes and it is suitable for routine use in clinical chemistry laboratories. Data for sample stability and test characteristics are given. A reference r nge of 20—180 μg/l elastase in plasma was deter-mined. The diagnostic significance of granulocyte elastase levels in plasma in inflammatory diseases is dis-cussed. „PMN-Elastase Assay": Enzymimmunassay zur Bestimmung des Komplexes von menschlicher Granulocyten-Elastase mit a/-Proteinaseinhibito
