Abstract: An immunohistochemical staining apparatus for carrying out immunohistochemical staining includes a sample chamber (1) in which a primary sample (s1) comprised of a tissue specimen (t) to which a primary antibody (Ig1) is applied is disposed between a sample-side electrode (11) and an opposed electrode (12). The sample chamber (1) has first stirring means for noncontactlessly stirring the primary sample (s1) by applying for a first prescribed time period an alternating electric field adjusted so that the opposed electrode (12) is minus with respect to the sample-side electrode (11), and second stirring means for noncontactlessly stirring a secondary sample (s2) comprised of the noncontactlessly-stirred primary sample (s1) to which a labeled secondary antibody (Ig2) is applied by applying for a second prescribed time period an alternating electric field adjusted so that the opposed electrode (12) is minus with respect to the sample-side electrode (11).

Abstract: The apparatus of the present invention comprises: an excitation device which excites the measurement site with a local direct-current or alternating-current magnetic field, and a plurality of magnetic field detection devices which are disposed in proximity to each other to measure the magnetic field component that is perpendicular to the exciting magnetic field.
