Immunocapillarymigration : Use of fluorescein- and enzyme-labeled antibodies to quantify C-reactive protein.

The method is based upon the attachment of antibodies to a porous insoluble support and the subsequent capillary migration of the antigen-containing solution in the support. The antigen-covered area thereby obtained was visualized with fluoresceinor horseradish peroxidase-labeled antibodies. The height of this area increased with increasing antigen concentration. The method was used to quantitate C-reactive protein.
