Immunological measuring element

摘要

There is presented a novel immunological element suitable for an immunological assay of an antigen according to the so called two antibody method, which element having two separate sheets, one being a sheet for reaction in which the reaction for formation of antigen-antibody bounds is carried out and the antigen-antibody bounds formed are immobilized, the other being a F receptor sheet in which unreacted free labelled antigen is transferred at a controlled rate to be received for analysis. This element enables separation between the bounds and the free labelled antigen by a simple operation without cumbersome separation procedures and is also excellent in storability.
