摘要： An improved method for depositing metal particles on a marker which catalyzes the reduction of metal ions from a physical developer comprising a solution of metal ions, a molar excess of complexant in respect to the metal ions and a reducing agent. Said method being preferably employed for the detection of one or more components of an aggregate formed between a least one specific binding agent and its corresponding bindable substance by labelling at least one component of said aggregate with a marker and contacting said aggregate with a physical developer, whereby under influence of the marker a metal particle is formed which can be detected. Further the invention also relates to solutions and test-kits adapted for carrying out the above mentioned method.

摘要： The present invention is directed to a new assay procedure and improved solid phase assay devices for use with a so-called physical developer. The invention provides a new assay procedure for detecting the presence of an analyte in a fluid sample using a tracer having a metal label which signal is enhanced by applying a physical developer. The assay is performed with a device having a support for a test area and having attached thereto a binder specific for the analyte to be detected. The assay comprises the steps of directing the fluid sample and the tracer through a porous medium into contact with the test area at a controlled flow rate to allow binding of the analyte with the binder and the tracer to the analyte, directing a physical developer through said porous medium to amplify the signal generated by the tracer, and separating the device to allow the test area to be read. The invention further relates to devices and immunoassay test kits for carrying out the improved immunoassay procedure. A first device FIG. 2 according to the present invention has a support 4 having upper and lower surfaces and a test area on its upper surface. A removable filter 3 overlies the upper surface of the support. A second device FIG. 1 according to the present invention has a support 4 having upper and lower surfaces and a test area on its lower surface which is in contact with the absorptive layer 2.
