| 摘要 |
The present invention provides a method of detecting antigens, which compris es immobilizing an antigen to a solid support and contacting the solid support with a means for hybridizing a labeled dendrime r to the antibody, through an oligonucleotide complexed thereto. A directly oligonucleotide labeled primary antibody or an oligonucleotide labeled secondary antibody may be employed, and a conventionally labeled dendrimer can subsequently be hybridized to the oligonucleotide through one or more of the outer arms of the dendrimer. The present invention offers the advantage over conventional methods of antigen detection by providing multiple label molecules per antigen, thereby enhancing the observed signal associated with the label .
