Abstract

Immobilized proteins are widely used in the clinical laboratory, e.g., immobilized enzymes in assay for analytes such as glucose, uric acid and immobilized antigen and antibodies in immunoassay. In the enzymatic analysis the use of immobilized enzymes make these reagents recoverable and thus reusable and in most cases increases their stability and catalytic activity. In conjuction with bioluminescent enzymes (firefly and bacterial luciferases) we set up high sensitive flow methods based on the use of nylon tube coil as solid support.

All the NAD(P)/NAD(P)H dependent dehydrogenases (bacterial luciferase), ATP dependent enzymes (firefly luciferase) and oxidases producing H2O2 (peroxidase) can be immobilized and a large variety of analytes have been sensitively measured.

In the immunoassay the immobilization of an antibody facilitate the separation of the protein from other components in solution i.e. For example an antigen-antibody complex. The combination of immobilized antibody with luminescent detection of the antigen-antibody reaction gave very specific and sensitive immunoluminescent metodologies.
