  • Patent number: 5338358
    Abstract: Apparatus for dyeing tissues sampled from a living body for the purpose of observing immunoreaction of the tissues has a dyeing tray with a plurality of plateaus arranged in parallel disposition. A slide is so placed over each plateau that a wedge-shaped gap of capillary dimension is formed between the plateau and the undersurface of the slide to which a sampled tissue is attached. A liquid drip surface and a liquid discharge port are formed at one end of the top surface of each plateau. A liquid delivery port is formed on a side wall of the tray so as to communicate with the liquid discharge port. The liquid delivery port and the drip surface are always exposed. A dyeing liquid or a rinsing liquid is dripped onto the exposed drip surface and spreads into the gap for dyeing the tissue or rinse the relevant parts. After the dyeing or rinsing, the used liquid is sucked and discharged by way of the liquid delivery port.
