| 摘要 |
A sitting-drop microwell plate (10, 10A) has wells (11) for crystal-forming chemicals and adjacent to each well (11) a shelf-like depression (12, 12A) on which a biological or protein specimen will be located for the formation of a crystal by exposure to vapour from the chemicals. In accordance with the invention a carrier member in the form of a sheet or film (14) of a light-transmissive material or a capillary tube (19) is located on the base (20, 20A) of each depression (12, 12A) so that a crystal will form on or in the carrier member (14,19) and can thus be removed from the microwell plate (10, 10A) for analysis without handling the crystal. |
