Title: Container and method for inspection
Inventor: OGAMA ATSUSHI
IPC: G01N33/543
Filed: 1993-12-27
Abstract: PURPOSE:To inspect all HLA antigens by forming such a recessed section that the inclination of its upper part is steeper than that of its lower part on the slope of a container and fixing a sample to be inspected to the slope of the container, and then, housing carriers on the surfaces of which antibodies which can be bonded to the HLAs are immobilized in the container. CONSTITUTION:A container for inspection has at least such one recessed section that the inclination of its upper part is steeper than that of its lower part. A sample 32 to be inspected containing HLAs (human histocompatibility antigens) is fixed to the slope 31 of the container. Then carriers 34 on the surfaces of which antibodies 33 which can be specifically bonded to the HLAs to be inspected are immobilized are housed in the container and an antigen- antibody reaction is caused. The behavior of the carriers 34 after reaction varies depending upon the reactivity of the HLAs contained in the sample to the antibodies 33 immobilized on the carriers 34 and the difference appears as the difference of a pattern formed by the carriers 34. When the antigen- antibody reactivity is high, the antigens are bonded to the antibodies 33 and the carriers 34 are fixed to the slope. When the reactivity is low, the carriers 34 sink and gather together in a groove.
