Abstract
The micro-channel chip for electrophoresis of the present invention comprises a first substrate formed of a gas-permeable material and a second substrate formed of a gas-permeable or a gas-impermeable material, the first and the second substrate being glued together, the mating surface of either one of the first and second substrates having a sample-feeding channel having a port at both ends and an electrophoretic channel also having a port at both ends, the sample-feeding channel and the electrophoretic channel being allowed to communicate with each other via a narrower channel having a smaller cross-sectional area than those two channels. The micro-channel chip for electrophoresis of the present invention requires only one power source to perform electrophoresis and can use samples with minimum waste of their quantity.
