Abstract
A method and apparatus for detecting incipient fungal decay in wood is described. Anti-xylanase monoclonal antibody is immobilized in a defined capture zone to a polyester assay substrate. Anti-hemicellulase polyclonal-labeled latex particles (carrier zone) are applied at a position distant from the capture zone. Wood extract to be tested is applied to the end of the polyester substrate and allowed to flow laterally through the carrier zone and the capture zone. A positive test results when antigen in the wood extract is complexed by the labeled polyclonal and monoclonal antibodies to form an observable particle complex.
