Abstract:
The invention provides a method of assaying an antigen or antibody in a sample by bringing the antigen-or antibody-containing sample into contact with a support for agglutination reaction as sensitized with an antibody or antigen respectively correspond- ng to the antigen or antibody in said sample and jetermining the quantity of the resulting agglutinate precepitate, which comprises measuring the diam- eter of the precipitate by means of a one-dimen- sional image sensor capable of sensing, on a line passing the center of said agglutinate precipitate, the ntensity of the light from a light source after its passage through the agglutinate precipitate, and an apparatus for assaying an antigen or antibody in a sample by the above method.
Abstract:
There is disclosed a centrifugal separation case (1) assembly adapted to a continuous type centrifugal separation apparatus in which the twist of communication tube (15) used for injection of the liquid, for example the blood, and for discharge of the separated components such as the red blood cell etc. is positively prevented, further, the complete separation and the short time separation can be realized using the separation case (1), and the rigidity of the tubes (15, 16, 17, 18) provided for the injection and discharge is improved.
