Abstract: PURPOSE: To provide a wedge-shaped sample well to partition a sample lane, in which samples are held in an ultra-thin slab gel used in a vertical slab gel electrophoresis. CONSTITUTION: A comb 32 has a wedge-shaped end 38, and a well is formed where samples can be held individually. Notches in wedge shape are cut in the alternate serrations constituting groove 62 so that tapered teeth are formed in the vertical direction, wherein the well is made with a space formed between adjoining teeth 61. A gel encapsulation 11 holding the slab gel is formed from two plates 12, 13 to constitute complementary openings in wedge shape leading to the gel space. Only the part with teeth of the comb 32 is fitted in openings, and is contacted with the over exposed surface of the gel or plunged for a short distance. It may also be accepted that the comb is formed in a rectangular shape and grooves having different depths are provided so that a wedge shape is generated.
